The subgrid-scale estimation model for high Reynolds number turbulence

Abstract

We propose a formulation of the subgrid-scale estimation model in which the effects of the estimated subgrid scales on the resolved scales are obtained through the truncated Navier–Stokes dynamics and the calculation of the subgrid-scale stress tensor is not required. For high Reynolds number isotropic turbulence the model predicts the k−5/3 spectrum with the correct value of the Kolmogoroff constant.
