Unsteady propagation of premixed flames through nonhomogeneous mixtures and thermal gradients

Recent advances in the mathematical study of unsteady laminar premixed flames have required the imposition of nearly constant flame temperature. This condition disallows investigations into such fundamentally important problems as flame propagation into thermal gradients and regions of varying equivalence ratio. Here, a rational method of analysis is presented to derive asymptotic solutions for one-dimensional unsteady propagation of deflagration waves with O(1) flame temperature variations. The propagations of premixed flames down thermal and concentration gradients are studied as example problems.
