Method for computing turbulent flow using a near-wall eddy-viscosity formulation |
摘要 |
A technique that improves large-eddy simulation consists in replacing the instantaneous sub-grid scale eddy-viscosity (such as the dynamic Smagorinsky model eddy-viscosity) in the near-wall region with an eddy-viscosity computed from Reynolds Averaged Navier-Stokes eddy-viscosity and corrected dynamically using the resolved turbulent stress. The near-wall eddy-viscosity formulation is applied either with a wall stress model on coarse grids that do not resolve the wall or with wall-resolved grids coarsened in the wall-parallel directions. Reynolds averaged Navier-Stokes eddy-viscosity is computed either from a look-up table or from a simultaneous solution of a Reynolds Averaged Navier-Stokes turbulence model.
