In this work we hae shown that the subgrid model following from the renormalization group theory of turbulence is capable of describing turbulent channel flow. Although the resolution of all simulations was relatively modest (16×64×64), the results revealed an excellent agreement between theory and physical experiment in the range of variation of R* from 125 to 400. The model seems to give a faithful description of turbulence in the wall region including correct, approximately Reynolds-number independent value of the spacing between the streaks. More experiments are needed to investigate the quality of the model for higher Reynolds number flows and to determine the resolution requirements of this LES model as the Reynolds number increases.
