Abstract

A compressible, multiphase, one-fluid RANS solver has been developed to study turbulent cavitating flows. The interplay between turbulence and cavitation regarding the unsteadiness and structure of the flow is complex and not well understood. This constitutes a determinant point to accurately simulate the dynamic behavior of sheet cavities. In the present study, different formulations including compressibility effects on turbulence are investigated. Numerical results are given for two partial cavities on Venturi geometries and comparisons are made with experimental data.
