In cryogenic fluids such as LH2 or LOX, temperature depression of liquids due to latent heat of vaporization suppresses the growth of cavitation, which is called "thermodynamic effects of cavitation." Thermodynamic effects of cavitation are significant in these fluids, because they are generally operated close to the critical point and are also characterized by a strong dependence of vapor pressure on temperature. Owing to this phenomenon, the performance of the rocket pump, inducer and other hydraulic equipment is sustained. In this paper, the thermodynamic effects of cavitation are investigated numerically. To predict these effects, a cavitation model introduced by Deshpande et al. is improved. Using this model a sheet cavity around a 2-D hydrofoil is simulated and the dependence of the properties of fluids or Reynolds number on the thermodynamic effects of cavitation is analyzed. The numerical results explain the thermodynamic effects well.
