Abstract

This article suggests heat and mass transfer equations for a reacting solid, with due regard for its deformation and destruction. The equations are derived with account taken for the relationships of nonequilibrium thermodynamics. Deformations and stresses in a system result from a chemical reaction, which is taken into account through a change in the specific volume of the substance. The applicability of the suggested approach is illustrated by particular simple ignition models for high energetic materials. The models reveal new qualitative mechanisms: the dependence of ignition characteristics on the mechanical properties of materials, the influence of the manner of sample fixing on reaction initiation, and the mechanisms of damage accumulation in the reaction zone. It is shown that the solid-phase reaction zone structure is determined by the reciprocal influence of thermal and deformation processes as well as by chemical transformation.
