The applicability of numerical prediction method for cavitation around hydrofoil NACA0015 was studied in this paper. For the present study, the mixture fluid methods was adopted for mass transfer between phases. For validation of this approach, simulations for the following problems were carried out: (1) leading edge cavitation on a hydrofoil; and (2)Cavitation performance and flow field analysis for a hydrofoil NACA0015. A full discussion of the results is presented below. This paper modified cavitation mass transfer equation based on the Rayleigh-Plesset equation. The pressure difference, surface tension and the turbulence effects were considered in the new mass transfer equation on the basic of the evaporation and condensation mechanics in the micro-kinetic theory. According to the governing equations for mass, momentum, volume conservation, the hydrofoil NACA0015’s cavitation characteristic was calculated by the new model. The cell-central difference finite element method was employed to discretize the governing equations. The pressure coefficient was contrasted with experiment data to validate the model. The calculation data is identical to the experiment data. As the result, it’s shown that this method can be used for the prediction of the behavior of sheet cavitation of the hydrofoil NACA0015.
