Abstract

Using explosive to disperse the tiny inert particles and form a particle group with large kinetic energy is a special damage mode. The estimations for the movement process and dispersal range of the inert particles are significant in the studies on the explosive charge and mechanism of action. The movement process of the 710μm diameter spherical tungsten particles driven by explosive was simulated numerically. Through the simulation the initial velocity of the dispersed particle was estimated. Bases on the numerical simulation for the cases with different explosive-metal mass ratios and layers of particle, the influence of explosive-metal ratios on the initial velocity and the difference of motion among the layers of particles were discussed. The dispersal ranges of the particles were analyzed by the model on the moving particle in the flow.
