Critical conditions during the transition of a gasless combustion wave through an air gap

The features of high-temperature synthesis wave propagation through an air gap are considered experimentally and by calculation and theory. Cylindrical samples made from a charge of different compositions were used. Critical values of the air gap width were found, at which the combustion wave transition from one sample to another is still possible. Depending on the parameters of the reacting mixture, the effective radiation coefficient from the end surface of the burning sample was calculated on the basis of the constructed mathematical model, consistent with the experimental data.
