Abstract
Turbulence strongly influences transport and disperson of contaminants advected by velocity fields, especially in the case of fluids made of species which undergo chemical reactions. Large scale coherent vortices take a prominent part in mixing processes as demonstrated here from numerical simulations of two and three dimensional mixing layers. Phenomena are even more intricate for turbulent combustion because of the density variations which are induced by heat released from chemical processes. Moreover, supersonic conditions let pressure waves trigger specific flow instabilities. In order to model all phenomena involved in these gaseous streams, numerical methods have to be carefully selected since flow structures must develop spontaneously whatever they are, vortices or shock waves.
