High-temperature ignition of a reactive material by a hot inert particle with a finite heat reserve

The initiation of a reactive material by an inert particle at a high initial temperature and with a limited heat reserve is studied numerically. The possibility of using known ignition criteria to study the process are analyzed. The effect of burnout on high-temperature ignition by a particle with a limited heat reserve is studied. Four regimes of the process and the critical parameters separating these regimes are determined. __________ Translated from Fizika Goreniya i Vzryva, Vol. 45, No. 2, pp. 40–47, March–April, 2008.
