Analyses on the Effect of Hot Spot Density on Material Consumption Rate

There is an observed effect of an explosives constituent grain size and density on its performance. At the mesoscale, it is the outward burning of hot spots that controls observed performance. While statistical hot spot models can integrate the mesoscale behavior to macroscale simulations, it is unknown what the density of created hot spots is as a function of grain size and porosity. Simulating mesoscale hot spot distributions and varying hot spot density, we discuss the resultant performance as influenced by inter-pore distance and pore distribution.
