Abstract

A three-term reaction rate equation is used to develop a mesoscopic reaction rate model based on the pore collapse hot-spots for the shocked aluminized melt-cast explosives. The aluminum is considered to be inert during the shock initiation, and a mixing rule is introduced to determine the ignition parameters of a mixture composed of the matrix explosive component and aluminum. A shocked DNAN-based aluminized melt-cast explosive was numerically simulated. The numerical results of the distances to detonation and the times to detonation at different Lagrange locations are in good agreement with the experimental data, which indicates that the mesoscopic reaction rate model is available for describing the shock initiation characteristics of aluminized melt-cast explosive.
