Comparative numerical study of cavitation on a two-dimensional hydrofoil

We took a two-dimensional hydrofoil calculation model as the research object, and adopted the method of numerical simulation. The movement of the hydrofoil cavity in the cavitation process was obtained through the numerical simulation study on different cavitation models and turbulence models. The result showed: In different types of cavitation models, the cavitation process of this hydrofoil included the generation, development, fall-off, and burst of vacuoles, and the process showed obvious periodicity. The simulation result of S-S cavitation model was consistent with the actual movement. The S-S cavitation model can well simulate the flow around a hydrofoil in the cavitation process.
