A reduced asymptotic model is formulated in the limit of small inverse nondimensional activation energy, ε — 0. to describe the time-dependent behavior of a class of premixed deflagrations. The model is similar to the reaction-sheet or flamelet models of combustion but the difference lies in the range of propagation Mach numbers considered, and here the initial Mach number Aio and ε satisfy the scaling relation Mi = O(ε). The reduced model requires numerical solution, and example results relevant to deflagration to detonation transition are presented for a configuration in which a deflagration in this class is situated between a driving piston and a preceding reactionless shock wave.
