An asymptotic theory of condensed phase combustion with inert melting Original Research Article

We derive an asymptotic model for the propagation of a combustion wave through a mixture of solid reactants in the presence of an inert diluent which melts in the reaction zone. We show how melting affects the steady, adiabatic, planar flame speed and the structure of the combustion wave. We also investigate the effect of melting on the linear stability of the steady, planar solution.
