Different computational fluid dynamics (CFD) strategies have been developed to simulate, analyze and better understand cavitating flows. Based on homogeneous models, two numerical approaches using compressible and incompressible codes, are applied to capture large density variations and unsteady behaviours of cavitating flows. Simulations are performed on two-dimensional Venturi geometries and compared with experimental data. Local and global analyses are proposed and the necessity to account for compressibility phenomena is discussed.
