A new subgrid turbulence model for near-wall cells is proposed. The model is based on the method of wall functions and takes into account the pressure gradient (both positive and negative). The model includes a smooth profile of tangential velocity, a smooth profile of turbulent viscosity, and a special profile of the dissipation rate of turbulent energy. The profile of tangential velocity is combined from the experimental zero-gradient and separation profiles. The proposed model is implemented in CFD software FlowVision-HPC and is verified using 2D test cases. Flows past straight and curvilinear walls are studied.
Keywords: Navier-Stokes equations; turbulence model; wall functions; airfoil; computational grid with subgrid resolution of geometry.
