Abstract

A problem of the condensed transparent phase ignition by the pulse light flow, that heats the inert absorbing inclusion, has been studied. Absorbing inclusions burn out consideration is shown to be necessary under limiting conditions of energy supply into the hearth. A numerical solution of the problem is obtained by means of limitant method with non-explicit difference scheme with the reduction on each time step. Calculated dependence of the ignition threshold on the light influence length is in a good argument with experimental data on pressed lead azide ignition.
