Convective combustion is initiated when hot reaction products flow into a channel from the open end. Thus the mechanism of propagation of the convective flame front is determined not by processes of heating subsequent fuel layers as a result of thermal conductivity but rather by convective heat transfer from hot gases flowing into the channel at high velocity. Rapid flame propagation leads to the occurrence of very high pressures in the channels which, under certain conditions, are able to initiate detonation of the fuel. In this paper the authors investigate the propagation of convective combustion in cylindrical channels of a compressible solid fuel and present a mathematical model depicting the transient problem of propagation of a convective flame front.
