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.
