Description

AN APPARATUS, SYSTEM AND METHOD FOR UTILIZING THERMAL ENERGY CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit ofU.S. Application No. 62/019091, filed on June 30, 2014, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION [0002] The invention relates to the field of kinetic energy and thermal energy harvesting, mixing, vacuum and pumping technology, in which it is possible to organize the process of efficient kinetic and thermal energy harvesting and create thrust and vacuum by utilizing the interparticle kinetic energy of the liquids in a closed or an open loop.

[0003] Known method of heating liquids, includes an electric or steam driven pump, indirect and direct contact heat exchangers and jet apparatuses supplied with thermal energy from boilers or district energy systems, where liquids are heated by steam or hot water supply (see for example Reference-1: Oliker, I. Demonstration of Performance and Energy Efficiency of Fisonic Devices at the Con Edison Test Facility, NYSERDA Report #20346). The heated water is transported to the consumers (end users). After transferring the heating energy to the user, the cooled liquid/condensate collected in condenser and is transported in a closed loop back to the heat source by the pump and the cycle repeats again. Make-up fluid is provided to the system when the fluid is not returned from the end user. This method consumes a substantial amount of thermal and pumping energy for heating and transportation of the liquid.

[0004] Many jet-type devices for heating and transporting liquids, steam, gases and solid materials are used in the industry. These jet-type devices include Venturi desuperheaters, steam ejectors, jet exhausters and compressors, jet eductors and jet vacuum pumps.

[0005] The typical jet-type device consists of three principal parts: a converging (working) nozzle surrounded by a suction chamber, mixing nozzle and a diffuser. The working (motive) and injected (entrained) streams enter into the mixing nozzle where the velocities are equalized by exchange of energy and the pressure of the mixture is increased. From the mixing nozzle or multiple nozzles the combined stream enters the diffuser where the pressure is further increased. The diffuser is so shaped that it gradually reduces the velocity and converts the energy to the discharge pressure with as little loss as possible. The jet-type device transforms the kinetic energy of the working stream to the injected stream by f

WO 2016/004014

PCT/US2015/038509 direct contact without consumption of mechanical energy. The jet-type devices operate with high expansion and moderate or high compression ratios and require a continuous motive force.

[0006] During the interaction of two streams with various velocities an increase in entropy of the mixed stream takes place (as compared with an invertible mixing), resulting in the reduction of the pressure of the discharged stream. Therefore, typically the discharge pressure of the jet-type device is higher than the pressure of the injected stream but lower than the pressure of the working stream.

[0007] The disadvantage of jet-type devices is that jet-type devices use high level kinetic motive force to perform work, which degrades the outlet pressures, drastically reduces the effectiveness of initial energy input ratios and requires a continuous motive force. Therefore these devices cannot be used to escalate pressure to a higher output level. Other devices, such as devices that operate based on what is known as Fisonic technology can utilize a lower energy input and escalate the initial thrust and thermal load. Fisonic technology design achieves this by exploiting the two-phase flow’s very low Mach number and harvesting a minute amount (<0.1%) of the system’s thermal energy and converting it to kinetic thrust.

[0008] In the Fisonic device (“FD device”) the injected water/fluid enters the mixing chamber with high velocity in parallel with the velocity of the working stream The injected water/fluid is typically supplied through a narrow circumferential channel surrounding the working nozzle. The mixing chamber typically has a conical shape. The optimized internal geometry of the FD device causes the working and the injected streams to mix and accelerate, creating transonic conditions, breaking the stream into tiny particles and changing the state of the mixing streams into plasma conditions, and finally converting the minute fractions of the streams thermal energy to physical trust (pump head) with the discharge pressure higher than the pressure of the mixing streams. The main reason behind this phenomenon is the high compressibility of homogeneous two-phase flows. It was demonstrated that uniform twophase flows have more compressibility than the flows of pure gases. Hence the possibilities of the more effective conversion of thermal energy into the mechanical work in uniform twophase mixtures especially in the transonic or supersonic modes.

[0009] The sonic speed in such systems is much lower than the sonic speed in liquids and in gas. As one can see from Figure 1 the minimum sonic velocity takes place at the volumetric ratio of the streams of 0.5). The important feature of the FD device is also the independence of the discharge flow from the changing parameters of the end user system

WO 2016/004014

PCT/US2015/038509 downstream (such as back pressure), indicating that the FD device creates supersonic flow and there is no downstream communication past the Mach barrier (or upstream either).

[0010] Referring to Figure 1 it may be seen that when there is no liquid - the ratio equals one, if there is no gas - the ratio B equals zero. When there is 50% liquid and 50% gas (two phase flow) - the ratio B is equal 0.5 and the sonic velocity is much lower than in gases and liquids. The equation of sonic speed is as follows:

c2 _ (1) ^p [0011] Where: k = isentropic exponent, equal to the ratio of specific heats; P = pressure; p = density of the medium. For determining the isentropic exponent, the following equation was developed:

(2) k(k +1) - 2k -9---1----=k/?

[0012] Where: k g = isentropic exponent of gas in the mixture; ε = critical ratio of pressures.

[0013] As the result of exchange of motion impulses between the working and injected streams, the sonic velocity in the mixing chamber is reduced. The stream at the entrance to the mixing chamber (throat) has a velocity equal to or larger than the local sonic velocity. As the result of the stream deceleration the temperature and pressure at the exit of the mixing chamber increase. The pressure becomes higher than the saturation pressure at the saturation temperature of the mixture. At the specific design geometry, the discharge pressure can increase by few times higher than the pressure of the working media. The liquid phase in the mixing chamber has a foam type (plasma) structure with a very highly turbulized surface area, therefore the dimensions of the FD device are very small when compared with conventional surface type heat exchangers. It should be indicated that the FD is a constant flow device.

[0014] Substantial differences in the above described process take place at small injection coefficients. The reduction of the flow rate of the injected water/fluids at the constant steam flow rate leads to the increase of the water temperature to the saturation temperature corresponding to the pressure in the mixing chamber and, because of the

WO 2016/004014

PCT/US2015/038509 shortage of water for condensation of all steam, while the FD device’s heat exchange operation continues, its pumping performance is proportionally reduced. This mode determines the minimum injection coefficient. At this mode the operational and geometry factors influence the characteristics of the FD device. With the increase of the injection coefficient, when the flow rate of the injected water (as the result of the reduction of back pressure) is increased, the water temperature in the mixing chamber is reduced. At the same time because of velocity increase in the mixing chamber the water pressure is reduced. The increase of the flow rate of injected water leads to the reduction of the pressure at the entrance into mixing chamber up to the saturated pressure corresponding to the temperature of the heated water. Reduction of the backpressure doesn’t cause the increase of the water flow rate because further pressure drop in the mixing chamber is impossible. This pressure drop which determines the flow rate of the injected water can’t be increased. Further reduction of backpressure at this conditions leads to flashing of the water at the mixing chamber.

[0015] The cavitation of water in the mixing chamber determines the maximum (limiting) injection coefficient, ft should be noted that this operational condition is the working mode of the FD. The FD operates with high expansion and small compression ratios.

[0016] Recent analysis and testing of FD’s resulted in a conclusion that conversion of the internal (interparticle) energy of overheated liquid into the work can be achieved both with the presence of a “cold” heat-transfer agent and without it. Furthermore, under specific pressure values at the entrance into the apparatus and specific internal geometric parameters, the “cold” liquid itself becomes the two-phase medium before the pressure jump. From this phenomenon follows a principally important conclusion that under the desired conditions the internal (interparticle kinetic) energy of liquid could be transformed into useful work.

[0017] In addition to the foregoing, other subject matter disclosed herein relates to the production of mechanical work and in particular to direct contact heat exchangers producing heat, and hydraulic, pneumatic and steam turbines for driving electrical generators, hydraulic pumps, compressors, heat and two-phase pumps.

[0018] Many buildings in the United States and around the world use steam for space heating, cooling and domestic hot water supply. The steam condensate is sometimes returned to the steam generating source or discharged to the city sewer system In order to reduce the condensate temperature from 220F to about 11 OF (the city sewer requirement) the condensate is mixed with cold potable water. Such systems operate with substantial

WO 2016/004014

PCT/US2015/038509 electric, heat and water losses and sewer discharge rate. All discharge rates are assessed and paid for.

[0019] Existing alternative sources for waste water use for electricity production include geothermal, solar thermal and bottoming cycles of large steam (fossil and nuclear), reciprocating internal combustion and diesel power plants, chemical processes, and various industries. Typically, the energy in boiling waste water is transferred to a thermodynamic working fluid (binary cycles) to generate electrical power. Because the water or other waste streams are only under moderately high temperature and pressure, the working fluids operate in the two-phase region with low energy conversion efficiency (15 to 20%) and often suffer from poor durability.

[0020] In 2000 the California Energy Commission sponsored a project (CEC-5002005-079) which briefly (for operational intervals of minutes) demonstrated that a twophase turbine with a long curved reaction expansion nozzle could operate at turbine efficiency close to 50%. The turbine used water heated to 435 °F and 350 psig. The principal difference of the proposed invention from the above turbine is the use of low temperature readily available renewable waste liquids and gases and application of advanced transonic nozzles capable of creating very high discharge pressure trust.

[0021] A two-phase reaction turbine for obtaining mechanical energy is known, which includes a radially outward flow turbine having a rotor with nozzles which extend from an inner inlet passage to the rotor periphery with a substantially constant pressure drop per unit length of nozzle, with a first order surface continuity along the surface of each nozzle and with a nozzle profile which allows two-phase flow without substantial lateral acceleration. The turbine also has an outer casing which is rotated by flow entering the casing openings creating an additional mechanical work.

[0022] The known reaction turbine has the disadvantage that it is not possible to obtain the maximum mechanical energy for the turbine from its rotor, since the torque generated in the rotor during flowing out of the working medium from its channels is limited by the discharge pressure of the environment.

[0023] A two-phase reaction turbine for obtaining a mechanical energy is known, which includes supplying a working medium into the channel of the rotor of the turbine and acceleration of the working medium during flowing out from the channels in one direction along a circumference perpendicular to the radius of the rotor with providing of rotation of the rotor.

WO 2016/004014

PCT/US2015/038509 [0024] The disadvantage of this known method is insufficiently high quantity of obtained mechanical energy because during the flowing out of the working medium through four channels of the rotor and its supply into a space formed by the casing in the form of the blade turbine around the rotor and flowing out through the openings in the casing between the instant of the turbine, the working medium located between the blades in instant of contact with streams of channels of the rotor is expelled, knocked out”, being accelerated to the speed of the stream from the channels of the rotor, for which a part of energy of the stream is used. During flowing out through the openings in the casing in the form of a radial blade turbine, there are losses for acceleration of the working medium in radial blades from centrifugal forces. In addition, there are losses for ventilation during circulation of the working medium between the blades due to flowing out through openings in the casing. Also, from the rotating casing in the form of a radial blade turbine, the working medium flows out with a speed which is significantly different from the speed of rotation of the casing, which leads to losses of energy.

[0025] A jet reaction turbine is also known, which has a working wheel formed as a tube with a closed end, connected coaxially with the shaft, arranged with a possibility of rotation, with at least one pair of pipe with open ends radially fixed on the tube at opposite sides, a casing arranged with the possibility of rotation and surrounding the wheel, a housing which surrounds the wheel and the casing and has openings for arrangement of the shaft, and nozzles for supplying and discharging of the working medium. At least one pair of pipes with open ends is fixed on the casing at the opposite sides. The casing and the working wheel are arranged on the same shaft.

[0026] The disadvantage of this known turbine is its fixed connection of the casing and the working wheel arranged on the single shaft, and to rotation of the working wheel and the casing in one direction, that provides obtaining of mechanical energy only from one casing, while pipes of the working wheel are only throttling the pressure of supply of the working medium by the elements of the turbine, which leads to useless losses of energy and low turbine efficiency.

[0027] A radial turbine with two shafts is known, which has a Segner wheel formed as a tube with a closed end connected coaxially with the shaft and arranged with the possibility of rotation, at least one pair of pipes fixed on the tube radially at opposite sides and having open ends which are bent in opposite sides from their axes, wherein the axes of the bent open ends of the pipes are perpendicular to a plane extending through the axes of the pair of pipes and the axis of the tube, wherein in a wall of the pipe openings

WO 2016/004014

PCT/US2015/038509 corresponding to the pipes are provided, a casing is connected coaxially with the shaft and arranged with the possibility of rotation and surrounding the Segner wheel, a housing surrounding the Segner wheel and the casing with openings for arranging the tube of the Segner wheel and shafts of the Segner wheel and the casing, and a nozzle for flowing out of a working medium. The casing is formed as a blade turbine.

[0028] The disadvantage of this known turbine is that in the casing formed as a blade turbine the blades are fixed to the disc along its end, which increases a centrifugal load on the blades due to an additional moment and an assembly of fixing of the blades is incapable of bearing a high load, that requires a reduction of circumferential speeds of the blade turbine and decreases the efficiency of the blade turbine. For passage between the blades, a stream of the working medium from the nozzles of the rotor must be directed to the blades at a certain angle which is determined by the shape of the blades and the shape of the stream from the nozzles. In the known turbine the stream of the working medium from the nozzles is supplied onto the blades under different angles, which on an average leads to increased angles acceptable to the turbines with a separate nozzle apparatus and to decrease of the efficiency.

[0029] The use of a hollow rotor (Segner wheel) leads to losses for friction due to generation in a hollow of the rotor a circulation of the working medium which is entrained due to viscosity on the walls and an opposite flow in a medium part of the hollow of the rotor (Segner wheel), or in other words the formation of a pair whirl. As a result the power taken from the rotor with the hollow is lost. With a partial supply of a working medium to the casing (blade turbine) from four nozzles of the rotor (Segner wheel), which rotates in an opposite direction, the working medium located between the blades at a low pressure in a moment of contact with the streams from the nozzles of the rotor, is expelled, knocked out”, being accelerated to a speed of the stream supplied from the nozzles of the rotor, for which a part of the energy of the stream is used.

[0030] In the casing (blade turbine) there are losses for acceleration of the working medium in radial blades from centrifirgal forces. In addition, there are losses for ventilation due to circulation or the working medium between the blades during flowing out through the openings in the casing. Also, from the rotating casing in form of a blade turbine, the working medium flows out with a speed which significantly differs from the speed of rotation of the casing, which leads to energy losses.

[0031] The known turbine also has a complicated construction and a complicated technology for its manufacture due to the use of a blade turbine as a casing.

2015284297 15 Feb 2018 [0032] A method of obtaining mechanical energy from a turbine is known, which includes supplying a working medium into channels of a rotor of a turbine, accelerating the working medium while flowing out from the channels in one direction along a circumference and normally to a radius of a rotor so as to make the rotor rotate, supplying the working fluid from the rotor channels into a space created within a casing above the rotor where it interacts by friction with the casing while flowing out through openings of the casing so as to accelerate in one direction and to make the casing rotate, forming the space in the casing closed and extending along a radius of the circumference along outlet openings of the rotor channels, and accelerating the working fluid flowing out through the openings of the casing along a circumference and normally to a radius of the casing in a direction opposite to a direction of flowing out from the rotor.

[0033] The disadvantage of this known method is insufficient high quantity of obtained mechanical energy because the nozzles are not of transonic type and do not provide additional thrust.

[0034] While existing systems described above are suitable for their intended purposes, improvements remain in the harvesting of thermal energy of the liquid while improving the efficiency of heat harvesting and providing reliable and stable operation of the system in a wide range of operating parameters, and while existing hot water and condensate collection systems are suitable for their intended purposes, the need for improvement remains, particularly in providing a system that improves the overall cycle thermal efficiency.

[0034a] A reference herein to a patent document or any other matter identified as prior art, is not to be taken as an admission that the document or other matter was known or that the information it contains was part of the common general knowledge as at the priority date of any of the claims.

SUMMARY OF THE INVENTION [0035] An embodiment of the invention includes a transonic two-phase reaction turbine for use with low and high temperature fluid flow mediums. The turbine includes at least two wheels that are configured to rotate in opposite directions, at least one of the at least two wheels being equipped with one or multiple kinetic energy harvesters.

[0036] According to one aspect of the invention, there is provided a transonic twophase reaction turbine having at least one rotor having a plurality of kinetic energy harvesters. Each kinetic energy harvester is disposed and configured to receive a first heat

2015284297 15 Feb 2018 carrier or heat carriers under pressure into a first nozzle, and to receive a second heat carrier into a second nozzle, the second heat carrier being colder than the first heat carrier, the second nozzle being disposed downstream of the first nozzle at a defined distance based at least in part on a flow, pressure and temperature of the heat carrier or heat carriers. Each kinetic energy harvester includes a mixing chamber between the first nozzle and the second nozzle configured to mix the first heat carrier and the second heat carrier to produce a twophase mixture, the second nozzle being placed at the defined distance from the first nozzle for producing an elevated discharge thrust. Each mixing chamber is configured to cause a pressure drop and deceleration of the heat carriers of the two-phase mixture to a velocity at which the two-phase mixture or at least one of the first heat carrier or the second heat carrier, or both, boils into a homogeneous two-phase medium with small bubbles, being highly compressible medium and with sonic condition of Mach number of more than 1. Each second nozzle is configured to converge and compress the two-phase medium flow, collapsing the small bubbles and changing the two-phase mixture into a non-compressible single-phase flow medium having increased kinetic thrust. Each kinetic energy harvester further includes a discharge section disposed downstream of the second nozzle, each discharge section being disposed and configured to discharge the single-phase flow medium having increased kinetic thrust to produce a reactionary pressure, higher than both input pressures of the first and second heat carriers, to drive the rotor in a rotational manner, wherein as a result each kinetic energy harvester produces thermal and kinetic energy.

DETAILED DESCRIPTION OF THE INVENTION [0049] Embodiments of the present invention provide for a hypersonic kinetic energy harvester, heat exchanger, mixer, dozator, homogenizer, pasteurizer, de-superheater, pump, flow/energy meter, emulsifier, thruster, expander and hyper condensate recycler (collectively herein referred to as a kinetic energy harvester, or KEH). Embodiments of the present invention create conditions for kinetic and thermal energy harvesting and substantial reduction of the thermal and pumping energy consumption by utilizing the KEH as herein described below. Embodiments of the invention provide for a KEH that converts the kinetic energy of the working fluid, supplied by the variable speed pump, into thermal and pumping energy, and provide reliable, stable and cavitation free operation of the system This provides advantages in substantially reducing the energy consumption of the existing pump and the conventional thermal energy supply. Embodiments of the invention may also be equipped with a deaerator which thoroughly removes from the liquid the non- condensible gases and substantially improves the thermal energy harvesting. The KEH may also operate without any external pump, as long as the fluids are present in the reactant mixing chamber and there is a thermal delta or a delta-pressure the KEH will start operating and will pump the fluids.

[0050] The performance of embodiments of the KEH are based on properties of twophase flows, first of all of their increased compressibility. In order to improve the effectiveness and thermal energy harvesting rate of the KEH, the cold liquid is initially preheated in a boiler, by district energy, solar, geothermal, wind, biomass, fossil, nuclear, waste or chemical energy, and is pumped (at the startup of the device) into the KEH. In the KEH the single phase liquid flow at subsonic conditions is transformed into a homogeneous

WO 2016/004014

PCT/US2015/038509 two-phase flow (plasma) which is transferred into a supersonic flow containing multiple microscopic vapor bubbles; then the simultaneous collapse of the vapor babbles in the supersonic two-phase flow takes place with resulting conversion of the two-phase flow into single phase flow, providing additional thermal energy and some pumping power. The capability and versatility of the KEH is such that depending upon end user requirements the KEH’s capability can be configured to meet specific applications.

[0051] Embodiments of the KEH consist of a diffuser equipped with geometry directing ribs. The diffuser is connected to a ring equipped with multiple tubes having helical ribs on inside surface. The ribs generate a swirl flow resulting in a centrifugal action that provides effective turbulization of the liquid. Afterwards, the liquid enters an open chamber. At this chamber the original liquid stream injects an additional liquid stream recirculating in the concentric external pipe from the discharge section of the KEH. The mixed flow further discharges into the coaxial nozzle located at the entrance of the Laval nozzle. After the Laval nozzle the liquid pressure is reduced to a value not higher than the saturation vapor pressure corresponding to the liquid temperature. At these conditions multiple vapor bubbles are formed in the liquid. The length of the Laval nozzle is a predetermined length.

[0052] At a predetermined distance from the Laval nozzle the liquid enters a geometry nozzle after which a counter pressure is applied causing emergence of a pressure surge with avalanche collapsing therein of the vapor component of the two- phase flow. In the course of the pressure surge, a range of oscillations is generated fostering collapsing of newly formed small vapor bubbles, which in their turn generate thermal energy and increase in the temperature of the liquid and a thrust of the liquid. At this point, part of the liquid is separated from the main stream and re-circulated back to the mixing chamber at the entrance of the KEH. The main liquid stream moves a predetermined distance and afterwards enters into a geometry ring/screen where additional thermal energy is harvested. Afterwards the liquid enters the conical discharge section from which the liquid with increased temperature is discharged in the piping system. The recirculation of a partial stream inside of the KEH allows providing reliable stable operational modes of the system in a wide range of system parameters (flow rates, temperatures and pressures).

[0053] The heated liquid is transported to the heat users. From the users the cooled liquid stream may recirculate back to the boiler or other heat input source. The return liquid can also pass through a deaerator in which the liquid is deeply deaerated. The removal of the non-condensable gases in the deaerator improves the energy harvesting process. In the repeated recirculation cycles the major heat input and pumping power are provided by the

WO 2016/004014

PCT/US2015/038509

KEH and the heat input of the boiler and the pumping power of the pump are substantially reduced. When the liquid is not returned from the customer, make-up liquid is provided to the KEH.

[0054] The dependence of the jump pressure, P₂, from the pressure before the jump inside of the device (Pbj) is described by the following equation:

(3) P₂=kP_wM²...

[0055] In the transonic or over sonic flow the homogeneous two-phase stream is achieved by the reduction of the sonic velocity which permits to achieve the Max Number equal or higher than one (M > 1) at low stream velocities.

[0056] The work balance of the KEH is described by the following equation:

(4)

Where:

k = Cp/Cv,

C p = specific heat at constant pressure; C_v = specific heat at constant volume; w, i, d Subscript denoting the following parameters of the working, injected and discharge streams: P= pressure and V=specific volume; u = injection coefficient equal to the ratio of injected and working flow rates.

[0057] The specific characteristics of the KEH are closely related to the geometry of the mixing chamber. The discharge pressure (Pd) after the KEH is presented by the following equation:

(5)

P_rf=P

[0058] Where: T _vv| = P j!Pw',fw\⁼ cross section of the working nozzle exhaust; /3 = cross section of the mixing chamber exhaust; K| = working stream velocity coefficient; φ₃ = diffuser stream velocity coefficient; T _wc = P _c / P _w = ratio of pressure in the critical section of the working nozzle to the working pressure; Awl ~ ratio of the velocity

WO 2016/004014

PCT/US2015/038509 of working stream at adiabatic flow to the critical velocity; f_wc = cross section of critical section of the working nozzle; u = injection coefficient.

[0059] The relationship between the pressure at the entrance in the mixing chamber (P2) and the injection coefficient is determined from the following equation:

P? i 2 | f /p» | _U_(i _{+ M})²

Λ Ρ» 2 (ξ,+lj ( fi J [0060] The equation of energy conservation for the medium with any compressibility is:

(7) dq= (^K/k-l) P du + l/(k-l)*u*dP + dqmp [0061] For an incompressible fluid (k—>x. dv=0), that moves in the adiabatic channel, the only heat source is friction. An incompressible fluid cannot serve as working medium for the conversion of thermal energy into the mechanical work. The situation is different when the equation (7) is applied to the cross section of the flow at the border of the pressure jump, where on one side the highly compressible two- phase mixture of fog-like structure is located, and on other side of the section of the pressure jump a single-phase liquid with the small bubbles of steam (gas) is located.

[0062] The conditions of the heat balance in the pressure jump mode are:

(8) Pid( 1 - β )*Δς=ρ₈*β*Γ (9) Aq = (p_g/pig)*r*(M² - 1) [0063] Where: r = the latent heat of phase change. From the analysis of equation (9) the several conclusions may be made. First, At M< 1, Aq< 0 - is the well-known process of evaporative cooling of liquid. Second, At M= 1, Aq = 0 - is the phenomenon of degeneration of turbulences described, respectively, in Reference-3, Vulis, L. A.,Thermodynamics Of Gas Flows, Gosenergoizdat M, L. 1950, for the internal problem of a gas moving with the near-critical speed close to the exit section of cylindrical channel, and in Reference-4, Fisenko, V.V. and Sychikov, V.I., On The Compressibility Effect On The Hydrodynamics Of Two-Phase Flows, Journal of Physical Engineering, 1977. V. 32, N°6., for the exterior problem of the flow around cylinder of the near sonic flow of gas. For the uniform two-phase mixture the problem was addressed in Reference-5, Gukhman, A. A., Gandelsman, A.F. and Naurits, L.N., On The Hydraulic Resistance In The Supersonic Zone

PCT/US2015/038509

Of Flow, Energomashinostroenie, 1957, N°7. Finally, At M> 1, Aq >0 - is the phenomenon, which was addressed in Reference-6, Potapov, U.S., Fominskii, L.P.and Potapov, S.U. Vortex Energy, www.transgasindustry.ru/books, by U. Potapov under a certain internal geometric influence on the fluid flow.

[0064] Under the controlled geometric, thermal, expense or combined influence on the fluid flow the maximum possible release of thermal energy by the internal energy of liquid is described by the following equation:

(10)

Aq = (AP/pid)*(M²/k- 1) [0065] Where: ΔΡ= differential between the pressure in the jump and the back pressure of system where the generated energy is supplied; and, pld = the density of liquid at the exit from the KEEL [0066] Experiments have demonstrated that by changing the internal geometry of the KEH, temperature, pressure, chemical composition, adding sound waves, electric stimulation, configuration of piping, combination of gases and liquids and gravity forces, can change and enhance the device parameters and increase substantially the harvested thermal energy and pumping power.

[0067] One embodiment of the KEH 20 is illustrated in Figure 2 and Figure 3. A liquid 1 is pumped and initially preheated in a device 22, such as but not limited to a boiler, by district energy, solar, geothermal, wind, biomass, fossil, waste or chemical energy for example. It should be appreciated that while the embodiment described herein references a linear construction of the KEH, the claimed invention should not be so limited. In some embodiments, the KEH is configured in the shape of a 360 degree ring torus for example. After heating, the liquid 1 is pumped (during start up) into the KEH 20. The KEH 20 includes of a diffuser 2 equipped with geometry directing ribs 3. The diffuser is connected to a ring 4 equipped with multiple tubes 5 having helical ribs on an inside surface. The ribs being configured to generate a swirl flow resulting in a centrifugal action to provides turbulization of the liquid. Afterwards the liquid enters in an open chamber 6. The length of the mixing chamber may be changed depending on the end use application. In chamber 6, a portion of the original liquid stream 1 is injected as an additional liquid stream 7. The liquid stream 7 is re-circulated in the concentric external pipe 8 from the exit of nozzle 11 of the KEH 20.

WO 2016/004014

PCT/US2015/038509 [0068] The mixed flow is further discharging into a first Laval nozzle 9 that compresses the single phase liquid stream 7. In one embodiment, one or more pressure sensors 36 are coupled to the first Laval nozzle 9. The pressure sensors 36 are configured to provide a signal indicative of the pressure in the first Laval nozzle 9 to liquid flow metering device 38. The liquid stream 7 is discharged into a second Laval nozzle 10. At predetermined distance from the second Laval nozzle 10, the stream enters a nozzle 11. In one embodiment, the pressure of the single phase liquid flow after the Laval nozzle is reduced to a value not higher than the saturation vapor pressure corresponding to the liquid temperature. At these conditions multiple vapor bubbles are formed in the liquid. After the nozzle Ila partial liquid stream is separated and re-circulated to the chamber 6 throughout the concentric pipe 8. It has been found that the recirculation of a partial stream inside of the KEH 20 allows providing reliable stable operational modes of the system in a wide range of system parameters (flow rates, temperatures and pressures).

[0069] In one embodiment, the nozzle 11 provides a braking effect on the two-phase flow and create counter pressure which causes emergence of a pressure surge with avalanche collapsing therein of the vapor component of the two-phase flow and conversion of twophase flow into single phase flow. In the course of the pressure surge, a range of oscillations is generated fostering collapsing of microscopic vapor bubbles, which in their turn harvest thermal energy and increase in the temperature of the liquid and a thrust of the liquid.

[0070] The main liquid stream moves some predetermined distance and enters into a ring/screen 12. Afterwards the main liquid stream enters the conical discharge section 13 equipped with ribsl4, from which the liquid with increased temperature and thrust is discharged in the piping system 15. In one embodiment, the piping system includes a conduit that flows a portion of the discharge flow from the KEH 20 back to a pumping device 34. In the exemplary embodiment, the pumping device 34 is a hydro turbine pump or a Fisonic jet pump.

[0071] It should be appreciated that the KEH 20 may include additional nozzles or inputs that provide for the supply of additional liquids and gases for mixing with the main liquid stream and creation of homogeneous mixtures and emulsions.

[0072] In one embodiment, the piping system 15 can be equipped with a flash separator 24 where the heated water is flashed, steam is separated and supplied to an end use application 26, such as a building steam heating system for example. The separator is connected to a KEH 20, which reduces the pressure in the separator and provides the water flashing conditions.

WO 2016/004014

PCT/US2015/038509 [0073] The heated liquid or steam is then transported to the end use application 26. Once the thermal energy is extracted from the heated liquid or steam at the end use application, the cooled liquid or condensate stream is re-circulated back to the boiler 22 or other heat input source. The return recirculation line may also be connected to a deaerator 28 where the liquid is deeply deaerated to provide removal of non-condensable gases, make-up and liquid expansion lunctions. In one embodiment, the deaerator is also used as an expansion device. In embodiments where cooled liquid is not returned from the end user application 26, make-up water 30 is supplied to the system 32. In the repeated recirculation cycles the heat input and pumping power provided by the KEH 20 and the heat input of the boiler substantially reduce the requirements of pumps 34 of the system 32.

[0074] In one embodiment the KEH utilizes interparticle forces (kinetic energy of one-two- and multiphase medium) and intended for mixing, temperature increase, and creation of thrust and vacuum of liquids and gases. The system can include a heat input device in the form of a boiler, district energy, solar, geothermal, wind, biomass, fossil, waste or chemical energy, a pump (for initial start up) that is connected to the KEH, which creates the conditions for energy harvesting and thrusts the heated liquid to a piping system connected to the consumer in open or closed loop circulation of the liquid medium and it may include a deaerator. The technical effect includes a KEH configured for specific range of operation. In one embodiment, the thermal energy harvesting temperature range should be between 110C and 250C. The KEH is applicable to various industries, transportation, irrigation, disinfection, fire extinguishing, water/oil separation, mixing, cooking, heating, cooling and low quality energy utilization.

[0075] Experiments have demonstrated that by changing the internal geometry of the KEH, temperature, pressure, chemical composition, adding sound waves, electric stimulation, configuration of piping, combination of gases and liquids and gravity forces, can change and enhance the device parameters and increase substantially the harvested kinetic and thermal energy and pumping power.

This system can be used for building, industry, solar and other waste energy recovery. The KEHs are supersonic, condensing heat pumps, with an internal geometry that causes steam, water or other gases and liquids to mix and accelerate, converting a minute fraction of a fluid’s thermal energy to physical thrust (pump head) with the outlet pressure being higher than the pressure of the working medium at the inlet of the nozzle.

[0115] Embodiments of the invention overcome the limitation of existing systems by substantially increasing the electric generation efficiency, as illustrated in Figure 22, which presents a comparison of a proposed cycle with an existing cycle utilizing a conventional steam turbine.

[0116] Indicated in Figure 22 as “a-b-c-d-d”’ is an ideal Rankine cycle without superheat. The position of point “b” is determined by the maximum allowable degree of dryness of the steam.

[0117] Embodiments of the invention overcome the limitation of existing steam turbines. It is well known that for steam turbines with modern blades the required steam dryness should be 88 to 92%. At higher humidity, irreversible losses are rapidly increased, and the dynamic load on the blades associated with the nonequilibrium flow is also

WO 2016/004014

PCT/US2015/038509 increased. As a result, the turbine operates with low internal efficiency. Thus, the expansion of saturated steam in the steam turbine is limited by curves X and BC. In the exemplary embodiment, the expansion process begins from the lower boundary curve (corresponding to d’-b’ on Figure 22). The thermodynamic cycle in which the turbine operates corresponds to the contour of d'-b’-c-d-d’. If the working fluid in front of the turbine is not heated to the saturation temperature, the working process will correspond to the line e-k-m, and first the device will operate as a purely hydraulic device, and after reaching the state of point ‘k’, as a hydro-steam device. If the change in heat capacity is neglected, the ideal proposed cycle in the T-S diagram is represented in the form of a right triangle c-k-m-c. The thermodynamic analysis indicates that the electric generation efficiency of such cycle may reach 60 to 70%.

[0118] An embodiment of the invention allows generating electric power utilizing waste water or gas without use of fossil firels and associated pollution. The vast amount of waste water and gases from various industries currently released to the environment will become the source of environmentally clean, renewable generation of electric power and heat supply.

[0119] Embodiments of the invention can also be used as a desuperheater device, combining the working stream with various waste steam streams, resulting in a substantial energy advantage over an existing desuperheater devices.

[0123] In an embodiment, the low temperature or high temperature medium is received from, but is not limited to: waste water (heat recovery from cooling towers, condensers, exhaust and waste streams from industry), steam, gas, various fluids, chemicals, particles or their combination.

[0124] Embodiments of the invention may be used for obtaining green mechanical energy with minimum thermodynamic losses for driving electric generators, pumps,

[0126] In still further embodiments, the engine and heat exchanger may be used for electric, heating, cooling, pumping, metering, mixing, combustion, cleaning, hydraulic fracturing of deep shale rocks, emulsion, solar systems, environmental protection, chemical and nuclear reactors applications for pumping and cooling.

[0127] In an embodiment, the internal molecular bindings of the working medium are broken when passing through the reaction in the KEH. In an embodiment, the passing of the working medium through KEHs increases the medium discharge pressure and temperature. Thereafter the medium is introduced through the inner channel to the center of the wheel and or through a seal side nozzle connection to the drum of the wheel· Each branch of the wheel is provided with KEHs. The wheel begins to spin increasing the centrifugal force of the fluid entering the wheel drum creating higher pressure to the drum and speed to the KEH. The working medium pressure in the wheel branches rises, flow accelerates, gets into the area of low pressure in the expanding part of the KEHs and intensively boils. As a result the supersonic single-phase jet exiting at high pressure and velocity from the KEHs accelerating at the rate of 600 to 1000 ft/sec into a direct contact condenser that creates reactive trust, spinning of single or multiple shafts. The condensed steam creates vacuum and the enclosure is under lower than the atmospheric pressure, resulting in reduction of friction losses in the turbine. The turbine pully is operating as a pump removing the water to complete the turbine cycle, or heat supply to heat exchanger, boiler, district heating system, and other users [0128] In an embodiment, obtaining mechanical energy is achieved with minimum thermo dynamical losses by increasing the efficiency due to maximum use of multiple waste streams of thermal and kinetic energy of the useful working medium, flowing out from the KEHs of the turbine. This embodiment can also include an outer casing around the wheel, equipped with concave or other formed blades, and rotated by flow entering through the casing openings, providing additional mechanical energy. Because of the reactive forces exerted on the wheels, they will rotate in opposite directions. The energy can be controlled by electrical load coefficient exerted on two turbine wheels to provide the outer wheel is rotating with lower speed than the inner
