Large eddy simulation of turbulent channel flows by the variational multiscale method
Thomas J.R. Hughes, Assad A. Oberai, Luca Mazzei · Physics of Fluids · 2001
The variational multiscale formulation of LES is applied to two-dimensional equilibrium and three-dimensional nonequilibrium channel flows. Simple, constant-coefficient Smagorinsky-type eddy viscosities, without wall damping functions, are used to model the decay of small scales, an approach which is not viable for wall-bounded flows within the traditional LES framework. Nevertheless, very good results are obtained.
