The effect of radiation on the combustion wave propagation in a heterogeneous system

The behavior of integral curves has been theoretically investigated in the problem of combustion wave propagation through a heterogeneous model system. The effect of radiation heat transfer on the steadystate (possibly nonstationary) combustion modes has been considered. At sufficiently high but limited spaces between the plates in the system with quasi-homogeneous temperature distribution, the effect of radiation heat transfer can be significant at low retardation by the growing product layer, and the combustion velocity can be much increased by the decrease in the characteristic time of radiation. At the same parameters of heat transfer in the mode of high retardation, the effect of radiation is much weaker and the increase in the combustion velocity is negligibly small if the chemical reaction maximum appears at low temperatures and indexes of the initial substance conversion.
