Abstract

An analysis is conducted of various theoretical models for the combustion of condensed systems: combustion regimes involving the destruction and dispersion of solid, foaming of the melting substance, vaporization or sublimation of decomposing substances, decomposition and oxidation of propellant components in quasihomogeneous composite systems, and heterogeneous reactions in laminated systems (chemical arcs, sandwiches). The main combustion characteristics: burning rate, burning surface temperature, dependence of burning rate on pressure and initial temperature as well as on other kinetic, thermodynamic, and physical parameters, are studied analytically and numerically. Conclusions are made about the mechanism and the leading stage of the combustion, as well as the methods of varying the combustion characteristics of different condensed systems, including explosives and solid propellants.
