Regimes of detonation of solid explosives with nonclassical fast kinetics
Source abstract
Abstract
Detonation development in a system whose exothermal reaction kinetics depends on the rate of change of the specific volume is studied numerically. In the case of sudden compression, e.g., in a shock front, this kinetics leads to a finite degree of conversion. If the contribution of such fast processes is significant, detonation regimes that differ from the standard Zel’dovich-Neumann-Döring regime are obtained. The wave profiles qualitatively coincide with those obtained for some explosives by Utkin et al. The modeling confirms the importance of fast processes in the wave front.
