Abstract: A direct numerical simulation of two dimensional temporally developing compressible mixing layer with chemical reaction has been presented. A high order upwind compact scheme developed by the second and the third authors is implemented. The chemistry dynamics is introduced with a simplified global, single step, irreversible combustion model. The interaction of heat release and fluid dynamics is studied. The effects of the latter on the mixing growth, the coherent structure and the rate of product formed in the mixing layer are analyzed.

Key words: mixing layer, finite differ ence, simulat ion
