A finite volume method for the calculation of compressible chemically reacting flows
Abstract
Several efficient pseudo time techniques have been developed for calculating steady state chemically reacting flows. The techniques include the implicit treatment of the chemical source term, point implicit multiple grid accelerator and a constant CFL condition. It turns out that these methods can be viewed as ways of rescaling the equations in time such that all chemical and convective phenomena evolve at comparable pseudo time scales. Consequently the number of iterations needed to solve reacting problems is approximately the same as for nonreacting problems. The techniques are demonstrated for a simple dissociation model and a nontrivial H2  Air combustion model.
