Large eddy simulation of a fully turbulent plane channel flow

Abstract

The development of a code for the large eddy simulation of wall bounded turbulent shear layers is described. The numerical approach selected is a finite difference discretization of the filtered Navier-Stokes equations, where the unresolved part of the turbulence is introduced through the Smagorinsky model of subgrid viscosity. A systematic study of the influence of mesh resolution, wall boundary condition and formulation of the advection term was performed for the case of a fully turbulent plane channel flow.
