摘要
Liquid-vapor phase separation in reservoirs for cryogenic liquid propellants in space vehicles at zero gravity conditions is achieved through a system including a unique heat exchanger. A mixed phase inlet stream is partially separated by centrifugal force imparted to the stream by swirl inducers as the stream enters the inlet of the heat exchanger. Lesser density components are provided to the interior of a spiralled tube forming part of a heat exchanger to be condensed therein by the higher density components which are applied to such tube within the heat exchanger. Heat transfer efficiency is mzximized by making the tube of rectangular cross section and providing liquid impingement jets active on three sides of the tube and by providing a baffle which forces the heat transfer fluid to further cool the tube by convection on the remaining side thereof.
