In this paper, unsteady 2D/axisymmetric simulations of cavitating flows are performed using a modified "Volume-of-Fluid" (VOF) method. Simulation of the cavitation is based on a homogenous equilibrium flow model. To predict the shape of the cavity, Navier-Stokes equations in addition to an advection equation for liquid
volume fraction
are solved.
Mass transfer
between the phases is treated as a sink term in VOF equation. The
numerical method
is used for different geometries in a wide range of cavitation numbers. Computed shapes of cavities were found to be in good agreement with those of the reported experiments. Simulation results also compared well with those obtained from analytical relations.
