Abstract.

A Large Eddy Simulation (LES) formulation is developed from the variational multiscale method. Modeling is confined to the effect of a small-scale Reynolds stress, in contrast with classical LES in which the entire subgrid-scale stress is modeled. All other effects are accounted for exactly. It is argued that many shortcomings of the classical LES/constant-coefficient Smagorinsky model are eliminated by the scale separation inherent ab initio in the present approach.
