Studies of Fast Reactions in Detonations
The time-dependent behavior of the flow in reaction zones of the detonating homogeneous explosives nitromethane, liquid TNT, and ideal gases has been investigated using one- and two-dimensional Lagrangian and Eulerian numerical hydrodynamics with Arrhenius chemical reaction. A general model for bulk decomposition of heterogeneous explosives, called Forest Fire, has been developed, which gives the rate of explosive decomposition as a function of local pressure. The model permits description of the process of heterogeneous explosive initiation, propagation, and failure.
