  • 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.

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.
