Dust Related Detonations

Abstract

Abstract. The paper presents a survey of works on the shock wave igni tion of dusts, and detonation in dust, hybrid, and gas mixtures containing inert particles. The dust· particles ignition in the incident and in the reflected shock waves are presented, and the effect of particles properties on the ignition process is discussed. Self acceleration to detonation, direct initiation of detonation, wave structure, and numerical modelling of detonation in dust mixtures is reviewed. Also the effect of the addition of gaseous fuel to the dust mixtures, and the addition of inert particles to the gaseous mixtures, on the initiation, structure, and limits of detonation in a such mixtures is discussed.
