On the Effect of an Anisotropy-Resolving Subgrid-Scale Model on Turbulent Vortex Motions

Abstract

In a large eddy simulation (LES), the flow variables are decomposed into a directly resolved grid scale(GS) component and an unresolved subgrid-scale(SGS) part that derives from the small-scale eddies. A canonical form of the governing equations for incompressible turbulence may be written.
