Abstract

A mechanism of detonation of emulsion explosives containing microballoons in finite-diameter charges is described. A parametric dependence of the detonation velocity on the charge characteristics is obtained. The fact that the reaction-zone width increases with decreasing charge porosity is explained. It is shown that the emulsion does not completely burn out at the Chapman-Jouguet point. Final formulas for calculating the reaction time and reaction-zone width are given.
