The presentation will be focused on the numerical predictions of the cavitating flow around a hydrofoil and marine propellers. The simulations are carried out using ANSYS-CFX, a commercial CFD (Computational Fluid Dynamics) code, and OpenFOAM, a OpenSource CFD toolbox. The cavitating flow is simulated using a so-called homogeneous model, where the working fluid is treated as a homogeneous mixture of two fluids, i.e water and vapour, behaving as a single one, and the mass transfer rate due to cavitation is regulated by the mass transfer model. Here, three widespread mass transfer models are alternatively used.
