Abstract
The incompressible Navier-Stokes equations constitute an excellent mathematical modelization of turbulence. Unfortunately, at- tempts at performing direct numerical simulations (DNS) are limited to relatively low-Reynolds numbers. Therefore, dynamically less complex mathematical formulations are necessary for coarse-grain simulations. Eddy-viscosity models for Large-Eddy Sim- ulation (LES) is an example thereof: they rely on differential operators that should be able to capture well different fl...
