Abstract:

Inducer is a key component of liquid rocket propulsion system to improve the performance of turbopump. It is well-known that rotating cavitation is harmful to turbopump, and even causes the launch failure of a rocket. Cavitation in cryogenic fluids can produce much latent heat, and has a thermodynamic effect because of thermal imbalance around the cavity. A numerical analysis of cryogenic fluids rotating cavitation in 2D blade cascade in inducer is performed with a mixture model based on Rayleigh-Plesset equation with the thermodynamic effect considered. The results indicate that the inlet pressure will decrease when take into account the ther
