Three-Dimensional Mathematical Model of Chemical Furnace

A mathematical model of gasless combustion in a “chemical furnace” mode was developed. The three-dimensional modeling of gasless combustion of a three-layer sample was performed. Numerical modeling was previously performed for non-stationary modes of gas-free combustion in homogeneous rectangular rods prepared from a mixture of two powder reagents with an admixture of low-melting inert metal powder. Further, the sample was considered as a combination of thermally coupled flat layers consisting of two mixtures of different chemical activity - the “chemical furnace” model. As a result of numerical modeling, various stationary and nonstationary combustion modes of the layered system were detected.
