Abstract
This work concerns the parallelization of an explicit algorithm for the simulation of compressible reacting gas flows, applied to supersonic mixing layers.
The reacting Navier-Stokes equations are caracterized by three tightly coupled physical phenomena, i.e. the convection, diffusion and chemical source terms. To compute the chemical source terms, full complex chemistry is used. By considering the elapsed time for solving the problem, the numerical treatment of the chemical source terms takes about 75% of the total execution time.
The main goal of the present work is to reduce the relative cost of chemical source terms calculation and also to optimize the global cost of the procedure resolution by the use of parallel computation.
This work took a large benefit of discussions with Yves Escaig (Mechanical Engineering Laboratory, INSA of Rouen)
