Experimental verification of discrete models for combustion of microheterogeneous compositions forming condensed combustion products (Review)

This paper presents an analytical review of modern quasihomogeneous and discrete models of gasless combustion. Particular attention is given to experiments that make it possible to distinguish between homogeneous and microheterogeneous regimes of this process. It is shown that in the cases where different theoretical models predict different behavior of the combustion wave at the macroscopic or microscopic level, experiments provide data in support of discrete models. The development of these models allows for a fresh look at the problem of controlling the propagation parameters of gasless combustion waves and the development of reaction compositions with specified strictly reproducible characteristics.
