An asymptotic model is derived for the nonsteady, nonplanar deflagration of energetic solids, such as nitramines, that experience exothermic reactions in liquid layers at their surfaces. The analysis takes into account the role of interphase heat transfer and the relative motion of gas and liquid in

โฆ Synopsis
The one-dimensional stability of the reaction-zone of a premixed plane flame is examined. The flame is described busing activation-energy asymptotics and it is shown that the stability of the reaction-zone depends on the Lewis number of the fuel. For the simple kinetic model considered, the critical Lewis number is one.

A simple model of a low Mach number deflagration wave is studied, with emphasis on the effects of a phenomenological heat loss term. It is shown by explicit construction that two quite different solutions, a fast wave and a slow wave, are possible in the adiabatic limit. In both cases the chemical r
