Abstract

A modification of Smagorinsky's subgrid model is proposed to account for the effects of anisotropic filtering. No new empirical parameters are introduced by the modification. Numerical experiments for a low Reynolds number turbulent channel flow have been carried out The results are in good agreement with results from direct numerical simulations. The effects of spatial resolution on the results of large eddy simulations are considered in some detail.
