Numerical Determination of the Scaling Exponent of the Modeled Subgrid Stresses for Eddy Viscosity leads to a scaling of . = 2/3. The current findings suggest to use Δ. for flow configurations operating at moderate Reynolds numbers. The resulting scaling exponent will be used to assess the quality of LES simulations of these configurations.

LES on Cartesian Grids with Anisotropic Refinement,prove the grid quality for LES are proposed. The resulting mesh then requires a fully unstructured discretization and a parallel polyhedral-based finite-volume solver is applied to perform simulations of the flow around several spheres.

Edwin D. McClanahan,Nils Laegreidsing a novel optimization technique. To test the validity of this approach, simulations were done with optimal LES models for the subgrid stress term which were derived from DNS statistical data, with very good results. The properties of subgrid models that appear to be important for this application are discussed.
