Abstract:
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.
