The combustion of energetic materials is governed in the solid or condensed phase mainly by the heat flow equation including phase transitions and exothermic reactions. In addn., in the gaseous phase the heat flow and the diffusion equation have to be considered for each species accounted for in the reaction scheme. Simplified models deliver some results on ignition delay and the dependence of the burning rate on initial temp. useful for practical application. The treatment of more complex aspects can describe transient behavior during ignition or the influence of externally supplied energy transfer.
