Abstract

Abstract

In the present work we studied the detonation of Al-RDX suspended in air using CE/SE. The two-phase detonation process of two dusts with different density were simulated and the effects of different particle density on the detonation wave speed and pressure were investigated. It was found that there is a linear relationship between the density ratio and the wave speed and pressure. The flow field evolution of the two dusts detonation in a complex channel was discussed. Compared with the single dust detonation, the detonation wave speed, pressure, and temperature of the two dusts detonation were obviously higher. It is shown that CE/SE is an ideal method at present to simulate the two dusts detonation and can provide useful reference for multi-dust detonation study.
