A robust CFD model is described suitable for general three-dimensional flows with extensive cavitation at large density ratios. The model utilizes a multiphase approach based on volume-scalar-equations, a truncated Rayleigh-Plesset equation for bubble dynamics, and specific numerical modifications (in a finite-volume solution approach) to promote robust solutions when cavitation is present. The model is tested and validated using hydrofoil, orifice, and pump flow applications.
