Ignition of a Reactive Material by Hot Gases,

Abstract

An asymptotic analysis is developed, describing ignition of a reactive solid suddenly exposed to hot gases. It is found that in the limit of high activation energy of the Arrhenius exothermic reaction, the chemical heat release occurs in a thin diffusive-reactive layer near the surface. The solution for this inner layer is then matched to the solution for the outer transient-diffusive region. An explicit formula for the ignition time is obtained.
