Definitions
- the invention relates to a method for increasing the pressure or Increase in the enthalpy of a fluid flowing at supersonic speed, with steam mixed with liquid and this mixture to supersonic speed is accelerated, after which a condensation surge is triggered.
- compressible two-phase flows behave in such a way that the State variables - with the exception of entropy, temperature and the resting temperature - change opposite in the subsonic and supersonic range (see E.Truckenbrodt, "Fluid Mechanics", Volume 2, Springer Verlag 1980, page 68). It means e.g. the supply of heat to a supersonic flow is a delay, but to a Subsonic flow an acceleration.
- condensation surge depends on the condensing surge Amount of water vapor (see Dr. Klaus Oswatitsch: Gasdynamik; Springer Verlag 1952, page 57).
- the condensation surge occurs when a fluid flows that is oversaturated Contains water vapor, and is the result of a sudden condensation of the Steam, which takes place very quickly and in a narrow zone, which acts as a "condensation impact surface" referred to as.
- the stability of the condensation surge against small disturbances in the direction perpendicular to their surface depends on the thermodynamic Condition of the steam before the impact. This just has to correspond to the beginning of a rapid condensation of the steam. A detailed Derivation of this process can be found in L.D. Landau and E.M. Lifschitz: Hydrodynamics: Akademie publishing house, Berlin 1966.
- the mechanism of the pressure increase is that condensation
- the vapor creates vacuum spaces from the speed of sound incoming fluid are filled up suddenly.
- the resulting kinetic Energy is converted into pressure.
- the strength of the pressure increase due to the condensation depends on the temperature difference between steam and liquid or from the liquid temperature when mixed with the steam and depending on the location of the shock.
- a steam accelerating nozzle, a feed nip for a liquid medium, a converging mixing nozzle and a diffuser is provided, a parallel flow section being arranged between the mixing nozzle and the diffuser in which a gap dividing the parallel flow section is arranged the length of the gap measured in the direction of flow between the 0.5 to 0.9 times the diameter of the parallel flow section. Because of this gap size it is achieved that a sufficient amount of additional liquid automatically is sucked in without the flow of the vapor / liquid mixture affect.
- Fig. 1 shows schematically the structure of the device according to the invention.
- Figs. 2 and 3 are diagrams in which the measurement results with those mentioned Device can be achieved, are shown graphically.
- Laval nozzle 1 with a Laval nozzle is designated, the convergent part 2 an opening angle ⁇ of about 25 - 60 ° and their divergent part 3 an opening angle ⁇ of about 3 - 20 °.
- This Laval nozzle 1 is a mixing nozzle 4 from convergent and cylindrical areas downstream, the convergent area ⁇ a Has angles of about 15 to 30 °.
- the length L1 of the cylindrical area is about 1 to 3 times its diameter. In this convergent area the diverging part of the Laval nozzle 1 projects into it, between the end of the Laval nozzle and the inner wall of the mixing nozzle a gap 5 is left open which mixes the liquid supplied via line 6 with the vapor becomes.
- a parallel flow part 8 to which a parallel flow part 9 of a diffuser 10 is connected downstream.
- the length L2 of the parallel flow part 9 is approximately 1 to 5 times its inner diameter D2.
- the opening angle of the divergent areas the diffuser 10 is approximately 15-45 °.
- the gap 11 is connected to an annular space 12, via which an Line 13 secondary liquid can be introduced into the flowing gas / liquid mixture is.
- these steps are triggered by that the steam passes through the Laval nozzle, the mixing nozzle and the diffuser.
- the steam in the Laval nozzle is accelerated to supersonic speed, wherein in the supersonic portion of the nozzle, the steam is released to a pressure that is less than atmospheric pressure.
- the over the outer contour of the Laval nozzle in the liquid sucked in the mixing nozzle mixes with the steam and it is created a homogeneous mixture of vapor and liquid that has a much lower speed of sound has as pure liquid or pure vapor (see "Guide through the Fluid Dynamics ", 8th edition, Friedrich Viehweg & Sohn 1984, pages 390 - 395).
- the mixture remains at supersonic speed. It is created in the gap between the mixing nozzle and the diffuser as a result of the acceleration of flow, a pressure that is less than atmospheric Pressure is.
- a throttle valve At the outlet of the diffuser is a throttle valve, not shown creates a back pressure, which is slowly increased until a vertical shock in the parallel flow part 9 of the diffuser, in which the Steam condensed completely via the shock. That leads to the desired one Pressure increase in the flow.
- a secondary flow is created via the gap 11 between the mixing nozzle and the diffuser introduced from liquid into the condensation zone before the compression shock, which further accelerates the condensation process and increases the pressure.
- the condensation process is completely completed with the shock.
- the condensation of the steam is associated with thermal energy, about 600 cal / g become free.
- the heat is derived from the liquid flowing out of the diffuser added.
- Table 1 The data in Table 1 are graphical in the diagram connected as FIG. 2 played. This diagram clearly shows the increase in pressure as a result added secondary liquid is recognizable. When using 7 bar, 7.5 bar or 8 bar steam pressure, the pressure in the flowing liquid rises from 17 bar up to 21 bar at 16%, from 18 to 23 bar at 18% and from 19 to 25 bar with 18% addition of secondary fluid.
