Pagination or Media Count:
This report makes preliminary steps in considering the detonation process for condensed explosives and the chemistry in the field of detonation products as linked physical entities. The desired end state of this research is improved control over explosive energy release. The report begins with a review of detonation physics with attendant algorithms for predicting detonation pressures. The second part of the report includes calculations of turbulent blast chemistry based upon an initial detonation solution for an HMX-based explosive. This chemistry includes a basic carbon soot model. Soot production is calculated over the first 27.5 microseconds of the blast event. Comparisons are shown between models of pure soot nucleation and nucleation with surface growth.
