Hybrid RANS/LES simulations of a cavitating flow in Venturi

Abstract : A numerical investigation of the behaviour of a cavita-tion sheet developing along a Venturi geometry has been performed using a compressible one-fluid RANS solver. The interplay between turbulence and cavitation regarding the unsteadiness and the structure of the flow is complex and not well understood. This constitutes a determinant point to accurately simulate the dynamic of sheet cavities. Various turbulent approaches are tested: a new Scale-Adaptive model (SAS) and the Detached Eddy Simulation (DES). 3D simulations are compared with the experimental data. An oblique mode of the sheet is put in evidence.
