摘要：
To investigate thermodynamic effect of inducer with cryogenic fluids, FBM turbulence model and a revised Kubota cavitation model with thermodynamic correction were applied into the numerical investigation of inducer cavitation in normal temperature water and liquid oxygen. The numerical method was verified by general agreement between the numerical results and experimental data of suction performance of inducer in normal temperature water. The results show that, compared with normal temperature water, the inducer cavitation with liquid oxygen is supressed. There is intense heat transfer for evaporation in cavitation area with liquid oxygen which decreases the local temperature, causing depression of saturation pressure, and hence the development of cavitation is suppressed. For the different temperature of liquid oxygen, a method was proposed to theoretically predict the suction performance of cavitating inducer. Two cavitation performance curves were established as a reference to predict other inducer cavitation performance at different temperature of liquid oxygen. The agreement between theoretical prediction results and numerical results has verified the predicting method. © 2021, Editorial Department of Transaction of Beijing Institute of Technology.
