  • In order to investigate the unsteady cavitating flow characteristics of the cryogenic fluids in the aircraft engine, Zwart cavitation model and large eddy simulation (LES) turbulence model were used to simulate the unsteady cavitating flow of liquid hydrogen around an ogive body. The results showed that compared with the experiments, the unsteady cavitating flow of liquid hydrogen around the ogive body could be accurately simulated by the numerical calculation model. The cavitation evolution process was divided into three stages: the growth of attached cavity, the development of large-scale cavity and the development of small-scale cavity. The analysis of flow field showed that the re-retrant jet was the main cause of the cavitation shedding and instability. Besides, the interaction between cavitation and vorticity was also analyzed. The vortex streching, vortex dilation and baroclinic torque terms were contributed to cavitation structures of leading and trailing parts of cavity, inside the cavity and at the interface between the cavity with mainstream and head of the re-retrant flow, respectively.
