## Abstract Large eddy simulation (LES) is based on separation of variable of interest into two partsβresolved and subgrid. The resolved part is obtained numerically using modified transport equation while the effect of the subgrid part is modelled using subgridβscale (SGS) models. In this paper we

In this article, large eddy simulation is used to simulate homogeneous shear ows. The spatial discretization is accomplished by the spectral collocation method and a third-order Runge-Kutta method is used to integrate the time-dependent terms. For the estimation of the subgrid-scale stress tensor, t
Recently, the e-expansion and recursive renormalization group (RNG) theories as well as approximate inertial manitblds (AIM) have been exploited as means of systematically modeling subgrid scales in large-eddy simulations (LES). Although these theoretical approaches are rather complicated mathematic
