Mechanical desensitisation of explosives (e.g. by a preshock) has important technological consequences for safety and performance. Many widely-used reactive flow models are not capable of reproducing the desensitisation observed in experiments such as double-shock particle velocity profiles. Improved models are under development, where we intend to incorporate enough flexibility to reproduce experimentally observed shock desensitisation while retaining plausible and computationally practical physical models for the equations of state (unreacted, partially-reacted and products), equilibration processes and reaction rate.
