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.
