Definitions

  • the invention relates to a method for increasing the pressure or increasing the enthalpy of a fluid flowing at supersonic speed, steam being mixed with liquid and this mixture being accelerated to supersonic speed, after which a condensation surge is then triggered.
  • compressible two-phase flows behave in such a way that the state variables - with the exception of the entropy, the temperature and the resting temperature - change in the opposite and supersonic range (see E. Truckenbrodt, "Fluidmechanik", Volume 2, Springer Verlag 1980, page 68). It means e.g. the supply of heat to a supersonic flow is a delay, whereas an acceleration to a subsonic flow is accelerated.
  • the condensation surge occurs when a fluid containing supersaturated water vapor flows, and is the result of a sudden condensation of the vapor that occurs very quickly and in a narrow zone called the "condensation surge surface".
  • the stability of the condensation surge against small disturbances in the direction perpendicular to its surface depends on the thermodynamic state 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 LD Landau and EMLifschitz: Hydrodynamik: Akademie- Verlag, Berlin 1966.
  • the mechanism of the pressure increase is due to the fact that the condensation of the vapor creates vacuum spaces which are suddenly filled up by the fluid flowing in at the speed of sound. 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 on the liquid temperature when mixed with the steam and on the position of the shock.
  • the supply of the additional liquid can advantageously be brought about by the negative pressure generated by the flowing mixture, as a result of which additional means for conveying the added liquid are unnecessary.
  • a steam acceleration nozzle, a feed gap for a liquid medium, a converging mixing nozzle and a diffuser are 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 is between 0.5 and 0.9 times the diameter of the parallel flow section.
  • This gap size ensures that a sufficient amount of additional liquid is sucked in automatically without impairing the flow of the vapor / liquid mixture.
  • Fig. 1 shows schematically the structure of the device according to the invention.
  • Laval nozzle 1 denotes a Laval nozzle, the convergent part 2 of which has an opening angle ⁇ of approximately 25-60 ° and the divergent part 3 of which has an opening angle ⁇ of approximately 3-20 °.
  • This Laval nozzle 1 is followed by a mixing nozzle 4 consisting of convergent and cylindrical regions, the convergent region ⁇ having an angle of approximately 15 to 30 °, the length L1 of the cylindrical region being approximately 1 to 3 times its diameter.
  • the diverging part of the Laval nozzle 1 projects into this convergent region, a gap 5 being left open between the end of the Laval nozzle and the inner wall of the mixing nozzle, via which the liquid supplied via the line 6 is mixed with the vapor.
  • a parallel flow part 8 adjoins the convergent part 7 of the mixing nozzle 4, which is followed by a parallel flow part 9 of a diffuser 10.
  • the length L2 of the parallel flow part 9 is approximately 1 to 5 times its inner diameter D2.
  • the opening angle of the diverging areas of the diffuser 10 is approximately 15-45 °.
  • a gap 11 is left, the gap width B of which is approximately 0.5 times the diameter D1 of the parallel flow part 8 of the mixing nozzle 4.
  • the gap 11 is connected to an annular space 12, via which secondary liquid can be introduced into the flowing gas / liquid mixture via a line 13.
  • a pressure is created as a result of the flow acceleration, which is less than the atmospheric pressure.
  • a back pressure is generated via a throttle valve, not shown, which is slowly increased until a vertical compression shock occurs in the parallel flow part 9 of the diffuser, in which the steam condenses completely via the compression shock. This leads to the desired pressure increase in the flow.
  • a secondary flow of liquid is introduced into the condensation zone before the compression stroke via the gap 11 between the mixing nozzle and the diffuser, as a result of which the condensation process is further accelerated and the pressure is increased.
  • the condensation process is completely completed with the shock.
  • the condensation of the steam is associated with thermal energy, which releases about 600 cal / g.
  • the heat is absorbed by the liquid flowing out of the diffuser.
  • the magnitude of the pressure increase that can be achieved by the additionally supplied liquid is illustrated using an example in Table 1.
  • Table 1 The data in Table 1 are shown graphically in the diagram connected as FIG. 2. This diagram clearly shows the pressure increase due to the added secondary liquid.
  • the pressure in the flowing liquid increases from 17 bar to 21 bar at 16%, from 18 to 23 bar at 18% and from 19 to 25 bar with 18% addition of secondary fluid.

Abstract

L'invention concerne un procédé et une dispositif pour accroître la pression ou l'enthalpie d'un fluide s'écoulant à une vitesse supersonique. Selon l'invention, de la vapeur est mélangée à un fluide, le mélange obtenu étant accéléré à une vitesse supersonique, à la suite de quoi un choc de condensation est déclenché. Avant le déclenchement du choc de condensation, une quantité supplémentaire de fluide est introduite dans le mélange s'écoulant à une vitesse supersonique.
