In this study, our cavitation model was employed and coupled with our simplified thermodynamic model to simulate the hydrogen cavitating flow field. Cavitation experiments on a 2D tapered hydrofoil in LH2 were selected to validate our model. The numerical solutions of the temperature and pressure distributions along the hydrofoil were compared and examined. The sensibility of the numerical solution of cavitation regarding to the cavitation empirical phase change constants was investigated. The empirical parameter for evaporation and condensation were corrected for hydrogen with comparable accuracy to experimental data. Additionally, corresponding of the degree of thermodynamic effect in hydrogen cavitation was discussed based on two types of thermodynamic parameter. In that, the temperature depression inside the cavity in both existing experimental data and present numerical result did not increase according to the increase in nondimensional thermodynamic parameter ∑*, which includes the thermal diffusivity with laminar boundary layer implicitly assumed. This indicates that turbulent effect has to be considered in the duration time of thermodynamic effect for a flow with a high Reynolds number, such as LH2 flow.
