It can be concluded that the modified SST model used in this paper has a good applicability in the unsteady cloud cavitation simulation.
Wang et al [5] studied the cloud cavitating flow around the hydrofoil using large eddy simulation (LES).
In the simulation results, the vapor volume fraction is used to illustrate cavity shape and the deeper color represents higher vapor fraction.
For numerical stability, CFD software tends to ignore the relative velocity between the gas and liquid phase and the thermal effect of phase change, and the dramatic density change of cavitation would be restricted.
From the above, the modified SST model used in this paper has a good applicability in the unsteady cloud cavitation simulation.
