Abstract

In this study, the Level set method is presented and applied to multiphase cavitating flows. Herein, this method is applied to flow solver that fully couples the mass, momentum, and transport equation; in numerical simulation, the Level set method with a compressive discretization scheme in both time and space to minimize the smearing of the free surface at the interface is used for simulation of nature and ventilated cavity. In these computations, three cases, including the steady nature flow around the axisymmetric body and the Clark-Y hydrofoil, and the ventilated cavitating flow around the disk are conducted, compared with the results obtained by simulation with the widelyused mixture model and experimental data, it is shown that, the Level set method is presented specifically to cavitating flows that decreases the interface diffusion where needed. Such an approach is a valid method that could reduce smearing at the cavity interface and also capture the sharp interface between different phases in an efficient and precise manner.
