Shock wave and detonation flow regimes in gas suspension of reacting gases and inert particles

Abstract

In this research, the interaction of shock waves (SW) with clouds of chemically inert solid particles of silica with a diameter of 100 μm in a hydrogen-air mixture is considered. Depending on the initial volume concentration of particles, three shock wave and detonation flow regimes are realized: 1. attenuation of the SW by a cloud of inert particles, 2. initiation of detonation behind the front of the SW reflected from the rigid wall, 3. initiation of detonation in a cloud of inert particles.
