Abstract

Abstract: In order to study the temperature and pressure effects of the detonation wave generated by dust clouds in the surrounding environment and its damage law, the two-phase flow model and space-time conservation element and solution element method are used to simulate the propagation of 3.0 m radius detonation wave in the air, which is formed by uniformly distributing the suspended aluminum dust with the equivalence ratio of 1 and the particle radius of 2 μm. The pressure reaches to maximum of 2.10 MPa when the detonation wave arrives at 3.0 m from the boundary of cloud, and then the pressure will decrease. The reaction of aluminum dust particles is completed without surplus at 4.7 m from the boundary of cloud. The fireball formed by the dust reaction move outwards to reach at 10 m from the boundary of cloud. The central area of fireball is a high-temperature and low-density area with temperature of above 3 500 K and density of 0.120 kg/m³. The overpressure reaches to 0.10 MPa when the propagation distance of shock wave arrives at 24.5 m from the boundary of cloud. The overpressure reaches to 0.09 MPa when the shock wave arrives at 28.0 m from the boundary of cloud, which can cause serious injury to the human body. Key
