Turbulence Model Study for Unsteady Cavitating Flows

摘要

A compressible, multiphase, one-fluid RANS solver was developed to study cavitating flows. The interaction between turbulence and two-phase structures is complex and not well known. This constitutes a critical point to accurately simulate unsteady behaviours of cavity sheets. In the present study, different transport-equation turbulence models are investigated. Numerical results are given for a Venturi geometry and comparisons are made with experimental data.
