摘要

Aluminum (Al) is added to explosive formulations based on TNT, RDX and HMX in an attempt to increase the blast energy and tailor the explosives’ blast-pressure pulse. The detonation pressure of these materials is lower than might be expected even though, while the subsequent reactions that generate aluminum oxide Al2O3 are very exothermic, sub-oxides AlO, Al2O, and condensed-phase products that form are endothermic and reduce the detonation pressure. Because the initial reactions involving HMX are both energetic and fast, and because the reactions involving the aluminum can be both net endothermic (due to a decrease in the gas volume) and also slow, a model for weak detonation is required to describe these explosives. We present an engineering analysis of a typical explosive in this class and demonstrate by means of accompanying numerical simulations, that a three component reactive flow model that has a fast exothermic step to intermediates, followed by a slower endothermic step to final products produces weak detonation.
