Abstract
The combustion process of the detonation products is a crucial factor for internal detonations of high explosives like TNT, RDX, HMX, or PETN. A thermodynamic model of aerobic combustion of detonation products, which extended the original model to include the simulation of the propagation of the detonation wave and which is implemented in the hydrocode SPEED, was presented. A detailed evaluation of the simulations further made clear that the required mixing of detonation products and air—and thus the complete combustion process—is strongly enhanced by the reflected shock waves traveling through the chamber. It can be stated that neglecting aerobic combustion in the investigated internal detonation events leads to a massive underprediction of the impulse delivered to the surrounding structure.
