Abstract

Detonation is the supersonic mode of combustion that occurs in munitions (military explosives and high explosives). These munitions result in blast waves that are hazardous to human life and structures. As a result, there is a high desire to mitigate these blast waves. One such method is to surround the explosive with mitigants (liquid, granular, and cellular porous material). For the safe storing and use of munitions, it is crucial to study the explosive dispersal of mitigant, the ensuing blast wave attenuation, and specifically, the mechanisms underlying this interaction. Current research involving mitigant blast wave attenuation is conducted in many configurations. The study aims to evaluate one configuration, shock tubes with particle suspension. Blast waves are simulated in the form of detonations initiated by DDT (deflagration-to-detonation) with mitigants in the form of dispersed particles. These dispersed particles included aluminum oxide, Al2O3, and aluminum, Al. The flame-flow interactions are experimentally studied using Particle Image Velocimetry (PIV) and pressure transducers. The effect of particle suspension on blast waves is revealed, portraying a decrease in mitigation performance.
