Abstract
This numerical work investigates the mesh influence in the near-wall area when a partial cavity develops and interacts with the turbulent boundary layer. Different meshes varying by the first cell size are compared, and unsteady simulations are performed with a two-phase one-fluid RANS solver. Numerical results are given for two Venturi geometries (quasi stable and unstable behaviour) and comparisons are made with experimental data.
