Convective combustion in the slot of an explosive charge

This paper presents the results of a study of the transition from layer-by-layer to convective combustion and to explosion for charges of advanced high-density explosives in a constant-volume chamber at a pressure of up to $\approx$ 60 MPa. Approximation of the results of the experiments with good correlation revealed a common parameter for explosives that characterizes the kinetics of convective combustion and made it possible to rank explosives according to their capability of transition from combustion to explosion. The results can be useful for computational modeling of explosion under accidental heating conditions.
