Abstract

We present the parallel computation of a combustion model with a two steps 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 that leads to intense computation. We show how to match to the frontal structure of the problem an adaptive domain decomposition of the PDE, and we construct a massively parallel algorithm. The algorithm has been implemented with high efficiency on the hypercube iPSC/860 and the Paragon by overlapping communications and computations.
