Titel:
A new approach to wall modeling in LES of incompressible flow via function enrichment 
Abstract:
A novel approach to wall modeling for the incompressible Navier-Stokes equations including flows of moderate and large Reynolds numbers is presented. The basic idea is that a problem-tailored function space allows prediction of turbulent boundary layer gradients with very coarse meshes. The proposed function space consists of a standard polynomial function space plus an enrichment, which is constructed using Spalding’s law-of-the-wall. The enrichment function is not enforced but ”allowed” in a c...    »
