Abstract : For a heterogeneous system with heat generation by solid-gas reaction and heat loss by conduction-convection, the mass oscillations at the interface can play an important role in ignition. A theoretical analysis was carried out for such a system in which the ignition process was defined in terms of a reaction mechanism involving transition from kinetic to diffusive control. In a numerical example it was shown how the ignitability of a system varies with initial temperature, oscillation frequency, and amplitude. The analysis offers some indication of the importance of various parameters on the ignition and extinction of an oscillating heterogeneous system. (Author)
