Title:
Scale-separating operators for variational multiscale large eddy simulation of turbulent flows 
Abstract:
A general class of scale-separating operators based on combined multigrid operators is proposed and analyzed in this work. The operators of this class are designed for variational multiscale large eddy simulation using a finite volume or finite element method. Two representatives are compared to discrete smooth filters, which are widely used in the traditional large eddy simulation literature; the comparison shows that they are not only theoretically different, but also yield considerable diffe...    »
