NUMERICAL-SIMULATION OF A COMBUSTION PROBLEM ON A PARAGON MACHINE

We present the parallel computation of a combustion model with a two s teps sequential reaction mechanism. Our main interest is the study of pattern formation, bifurcations and nonlinear interactions between the two chemical reactions; The combustion occurs in a frontal regime tha t leads to intense computation. We show how to match to the frontal st ructure of the problem an adaptive domain decomposition of the PDE, an d we construct a massively parallel algorithm. The algorithm has been implemented with high efficiency on the hypercube iPSC/860 and the Par agon by overlapping communications and computations.
