Detonation Kinetic Instability and Breakdown Phenomena

Abstract

As has been mentioned above, there are both explosives whose detonation is stable (one-dimensional) and explosives whose detonation is unstable (non-onedimensional, pulsating). Naturally, some questions arise: What is the mechanism of the pulsating detonation’s origin? Which processes in the pulsating zone cause complete energy release? What do the pulsations lead to: an increase in the total time of energy release in the wave front or its decrease? Do the pulsations in the detonation front boil down a “fine structure” of the ZND one-dimensional detonation complex? Which phenomena in the pulsating front determine its rearrangement in spherical detonation as well as in the course of SD transition to CJ detonation? What is the nature of the limits of propagation of a pulsating detonation wave?
