Abstract

During the last years the simulation of compressible viscous flows has received much attention. While the numerical methods were improved drastically — discontinuous flows can now be well resolved with high-order, non-linear, upwind schemes [1]; the computing times have significantly been reduced by implicit or multigrid techniques [2] — a satisfactory modeling of the Reynolds stresses is still missing. Thus, even if with the present generation of supercomputers, the computation of flows around complete aircrafts has become possible [3,4], the computation of realistic separated flows remains unpractical on complex geometries. In this paper, after a short description of the numerical procedure used for solving the Reynolds equations, experiments with a promising simple turbulence model [5] are discussed.
