Abstract
This paper presents the numerical simulation of gasless combustion of a sample as a combination of thermally coupled flat layers consisting of two different chemical compounds, which represent the model of a chemical furnace. The critical combustion conditions are established, depending on the volume ratio of mixtures in the sample or the content of reaction products. The time, velocity, and combustion modes of the layer composition are determined, depending on the volume content of the mixtures, the thickness, and the number of layers. The combustion wave propagation in view of “homogenization” of the sample with layer thickness decreasing at a fixed concentration of the components is considered.
