| A new subgrid model for homogeneous turbulence is proposed. The model is used in a method of Large-Eddy Simulation coupled with an EDQNM prediction of the statistical properties of the small scales. The model is stochastic in order to allow a "desaveraging" of the information provided by the EDQNM closure. It is based on stochastic amplitude equations for two-point closures. It allows back-flow of energy from the small scales, introduces stochasticity into LES, and is well adapted to non isotropic fields. A few results are presented. |
