Abstract
This paper describes the model of the propagation of solid-phase exothermic reaction in a layer between inert materials with various thermal and physical properties. The model is implemented numerically. The relationships between the ignition time and the model parameters, as well as the behavior of some energy characteristics under various conditions in time (heat reserve in the heated layer and excess of enthalpy). The influence of the thermal and physical properties of inert materials on the temperature distribution in the sample in stationary and nonstationary regimes is demonstrated.
