Abstract
The methods of mathematical modeling are used to explore the initiation of combustion of a large mass of a condensed mixture in the local contact with the end face of the burning layer. It is shown that the minimum width of the igniting layer is proportional to the width of the thermal front of the combustion wave. The coefficient of proportionality is determined by the initial temperature, heat, and activation energy of the reaction. The calculation results can be used to estimate the effective activation energy of the reaction that controls the combustion mechanism of a gasless system.
