Variants of projection‐based finite element variational multiscale methods for the simulation of turbulent flows

Abstract

AbstractSome variants of a three‐scale projection‐based finite element variational multiscale (VMS) method are studied for turbulent channel flow computations at Reτ=180. Different spaces for the large scales, two eddy viscosity models and two ways of discretizing the projection terms in time are explored. The results obtained with the resolved small scales in the definition of the eddy viscosity are very sensitive to the temporal discretization of the projection terms. The computations were performed on three grids commonly used in turbulent channel flow simulations. Copyright © 2007 John Wiley & Sons, Ltd.
