Abstract
The variational multiscale formulation of LES is applied to two-dimensional equilibrium and three-dimensional nonequilibrium channel flows. Simple, co nstant-coefficient Smagorinsky-type eddy viscosities, without wall damping functions, are used to model the decay of small scales, an approach which i s not viable for wall-bounded flows within the traditional LES framework. N evertheless, very good results are obtained. (C) 2001 American Institute of Physics.
