VISVE, a Vorticity Based Model Applied to Cavitating Flow around a 2-D Hydrofoil

In this study, a method solving the viscous vorticity equation (VISVE) and the mixture model, which introduces an additional transport equation for the vapor volume fraction, are coupled to predict the partial cavitating flow around a two-dimensional hydrofoil. The VISVE method is designed to be both spatially compact and numerically efficient in comparison with the commonly used RANS models. The cavitation is modeled by the Schnerr-Saucer or the Zwart-Gerber-Belamri models. The predicted vorticity, velocity, pressures and the vapor volume fraction are compared with those from a commercial RANS solver.
