EFFECTS OF CONDENSATION ON ROCKET NOZZLE PERFORMANCE
Abstract
A study was made of the part played by condensation as one of the mechanisms of energy transfer in the process of nozzle flow in a propulsion device. In order to confine attention to this particular mode of energy transfer, the working fluid and flow conditions are so chosen that the complicity of chemical kinetics is avoided. Equilibrium condensation is assumed, since from the point of view of heat impartation it represents an optimum condition which conceivably can be promoted by suitable additives. Both single and multicomponent working fluids are treated and the results are amenable to a single correlation which does not include the material properties explicitly, but is dependent only upon the states experienced by the working fluid through the process. The study is intended as a basis onto which other more complicated processes may subsequently be incorporated. As they stand, the results will find direct application to simple gas bottle low thrust devices used for attitude control in many spacecraft. (Author)
