Abstract

We are interested in the development of LES methods for compressible flows in complex geometries. Our starting point is a numerical scheme applying to unstructured tetrahedrizations, that is conservative, upwind of MUSCL type and vertex centered. We extend it to a low diffusion version stabilised with six-order derivatives. The new scheme is combined with two LES models, derived from the Smagorinsky model and the dynamic Germano model. The basic test case choosen is the flow around a square cylinder
