Heat and mass transfer at ignition of solid condensed substance with relatively low calorific power by a local energy source

Macroscopic laws of heat and mass transfer at gas-phase ignition of solid condensed substance with relatively low calorific power by a typical local energy source, namely, a small hot metal particle shaped as a parallelepiped, are investigated. The proposed model takes into account a group of interrelated processes of heat and mass transfer with thermal decomposition and chemical reaction in the interaction of solid and a source with limited energy content. The influence of the heat content of a local energy source on the characteristics of the process is analyzed.
