Calibration of mass transfer models for the numerical prediction of cavitating flow around hydrofoils and marine propellers
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.
