In this paper, the thermodynamic effects of cavitation based on the computational methodology of cavitation mass transfer has been considered in the prediction of cavitation performance of a hydrofoil in water at high temperature. A cavitation mass transfer model to study this phenomenon has been presented. The cavitation model was used to simulate the flow along a NACA0015 hydrofoil at different temperatures. The results were compared with experiments. From the distribution of the pressure coefficient, it can be seen that the simulation results with the improved model have the same trends and values comparing with the experiments. At low temperature, the length of the cavity area is nearly the same with experiment, but at high temperature, the calculated cavity length is slightly longer.
