Abstract:
The liquid rocket engine inducer characteristic is impact by working medium thermodynamic effect, especial for cryogenic working medium.The inducer cavitation characteristic could be improved by cryogenic medium thermodynamic effect, because which could suppress babble growing.However, the research for this issue still remain qualitatively in domestic study currently.Quantitative research for thermodynamic effect is necessary in order to understand inducer operation characteristic in cryogenic working medium.In this paper, a new cavitation model modified by thermodynamic effect has been deduced based on Rayeigh-Plesset equation.In addition, the model has been compiled as a computer program, which has been used as rocket engine inducer numerical simulation.The model has been improved applicable by comparing simulation and engine trial run results.
