Abstract
In this study, a simple model for two-dimensional (2D) cavitating flows with artificial viscosity is proposed. The governing equations are the unsteady incompressible viscous Navier—Stokes equations. The proposed method includes the combination of a source and a sink of vapour through a dissipation term. The comparison between the obtained numerical results for a 2D wedge and the numerical solutions and experimental data shows that the cavity characteristics are well simulated. It can be concluded that introducing an artificial viscosity term improves both the numerical stability and the convergence rate.
