Large eddy simulation and the variational multiscale method. (English)
[J] Comput. Vis. Sci. 3, No.1-2, 47-59 (2000). ISSN 1432-9360; ISSN 1433-0369/e

Summary: A large eddy simulation (LES) formulation is developed from the variational multiscale method. Modeling is confined to the effect of 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.
