Definitions

  • the invention relates to an equipment of relatively small size capable to generate more power per unit of fluid intake area, which can be integrated on land vehicles, river and sea ships, designed to convert the kinetic energy of a fluid into mechanical energy and / or electricity, by capturing and accelerating a fluid jet engine which is transferring energy to another jet of fluid, called ejected fluid, which at its turn acts the blades of a ring turbine built in a suction chamber, which leads a power generation system.
  • HAWT Horizontal axis wind turbines
  • VAVVT Vertical axis wind turbine
  • wind turbines are classified function of the principles of energy transfer, as follows:
  • Wind turbine that works by drag on the base of action and reaction force principle - the wind pushes the blades and the blades are pushing the wind resulting their rotation.
  • This type of wind turbines requires a control and positioning system to turn the blades toward the wind.
  • Small turbines have a vertical tail surface disposed opposite the rotor (fig. 2) which plays the role of positioning system but at large turbines there is a complex system of sensors and actuators that control and position the rotor into the wind.
  • VAWT Vertical axis turbines have the advantage that the rotor does not need to be pointed into the wind to be effective, such turbines operating regardless wind's direction.
  • VAWT can be either by drag or by lift forces.
  • the most common subtypes are Darrieus, Giromill and Savonius.
  • Blades with square or rectangular cross-section have a larger swept area for a given diameter than the circular swept area of a horizontal axis turbine of the same diameter.
  • the rotor starts to spin at a lower wind speed than horizontal axis turbines, so the majority of VAWT have an easy start without requiring additional energy.
  • VAWTs produce energy at only 50 % of the efficiency of HAWTs in large part because of the additional drag it have when their blades rotate against the wind, see Fig. 4. Versions that reduce drag produce more energy, especially those that funnel wind into the collector area. • The spinning speed of the blades cannot exceed the wind speed.
  • TWES Tornado -Type Wind Energy Systems
  • TWES wind turbines The main advantage of TWES wind turbines is the difference of pressure which occurs between the periphery and the center of the swirl. Thus it was found that in a swirl, its center has an accentuated low pressure area that can "attract” and “accelerate” non- vortex air masses at higher speeds then the speed of the wind which creates whirlwind.
  • the practical use of this concept lies in placing a turbine in the bottom center of a device or installation capable to generate a vortex flow, the turbine having an air intake located such as to "absorb" air masses outside the swirl. Besides the low pressure area was discovered to be favorable for spinning turbine also the rotation of the swirl behind the turbine's blades. For example we add figures 8 -14 which contains some TWES patented installations.
  • a wind turbine has to "process" effectively the captured wind, requiring to use a device that can accelerate as much possible the trapped air-flow, in conic inlet case to have the ratio between the surface of the upstream intake and the surface of downstream exhaust as high possible, while maintaining a surface of the upstream intake as small as possible in order to ensure a low aerodynamic opposition, and the turbine's rotor to have an optimum size in order to generate a sufficient torque and a rotational speed corresponding to the conditions offered by the "processed" airflow.
  • the technical problem solved by this invention is to provide an equipment capable to collect, accelerate and operate with high-speed fluid stream, which have a small coefficient of aerodynamic opposition and which can be easily integrated in the structure of land transport vehicles, river and sea ships.
  • the equipment according with the invention solves the technical problem by been composed by a fluid intake fitted with a device to control the flow of fluid and to shut-down the admission (ex. fiap-shutter system), which is directly connected with a conic nozzle, where the fluid flow is accelerated and sent through a supply pipe to an s ejector -type device as engine jet of fluid, which expands through a nozzle into a suction chamber and then released in the atmosphere through an exhaust nozzle or exhaust diffuser.
  • an annular turbine consisting of an annular rotor and an annular stator meant to direct the flow of absorbed fluid with the optimum incidence angle to the rotor's blades.
  • the engine jet of fluid drives the fluid from suction chamber resulting a low pressure area behind the annular rotor, so more fluid is absorbed in the suction chamber through an annular stator device which guides the absorbed fluid to rotor blades.
  • the sucked jet of fluid called the ejected fluid, acts the blades of the annular rotor which drives thru a crown gear or a pulley, mounted on the outer circumference of the rotor, an electric power generation system.
  • the equipment can be used both as a wind turbine and the hydraulic turbine, steam turbine, air - steam turbine - turbine that uses as engine fluid and ejected fluid any combination of technical fluids.
  • the equipment can be also integrated in the structure of trains as auxiliary wind generator to reduce fuel consumption or the consumption from electric grid, and on the decks structure of ships as auxiliary wind power generator to reduce fuel consumption.
  • Transmission on the outer circumference of the rotor allows a greater versatility in positioning and engagement of the power generation system in the sense that a generator which provides efficient conversion up to a certain rotation speed may be located on one side and another effectively functioning in another rotation speed range can be placed on other side, those may be driven alternative by turbine's rotor function of its working conditions.
  • the equipment according to the invention is made up from an ejector type device equipped with an engine fluid supply pipe connected to a conic nozzle which accelerates the fluid flow captured by means of a intake fitted with a device meant to control the flow of fluid and to shut-down the admission.
  • the engine fluid releases in a suction chamber where drives more fluid creating another jet of fluid called ejected fluid and then together are exhausted through an exhaust nozzle or exhaust diffuser.
  • the ejected fluid is absorbed in the suction chamber through an annular turbine built in the suction chamber, consisting of an annular rotor and an annular stator device meant to direct the flow of ejected fluid in the optima! incidence angle on the rotor's blades.
  • the annular rotor has a crown gear or a pulley located on the outer circumference which leads a power generation system.
  • the ejector type turbine can have additional features, such as:
  • the ejected fluid intake will be equipped with tubing and / or designed fairing meant to ensure the efficient management of the air flow from the outside of vehicle body or train to the suction inlet.
  • the equipment's components will be fitted with brackets or constructed to be functional assembled or functional embedded in the structure and construction of electric cars or trains.
  • the equipment When using as auxiliary wind generators on the deck of ships or boats the equipment will be fitted with a mounting bracket designed to provide fixation and its connection to the ship's systems.
  • the conic nozzle When used as a hydraulic turbine, steam turbine, steam - air turbine, etc. the conic nozzle can be removed, the supply pipe for engine fluid may be connected to a feed pipe under pressure, and the start / stop system and regulating the flow consists of two valves manually and / or electrically operated, one located on the supply / feed pipe and one on the discharge pipe. Also the ejected fluid intake should be submerged and the around area should be specifically prepared in order to reduce the effects of sediment deposition, clogging, etc. We recommend blow-off the fluids into the atmosphere. The equipment will have a support system designed to provide fixation and anchoring it in the optimum position.
