In order to achieve directional dispersing of metal particles, a detonation-driven model placing metal particles and explosives together inside a rigid pipe was developed in this study. The one-dimensional detonation wave theoretical analysis was conducted to explore the relationship between the dispersing velocity and the mass of particles and explosives. Moreover, the three-dimensionl finite element simulations were performed with mass ratio of explosive/ particle at 0.5:1, 1:1 and 2:1 respectively, while the particle diameter was 0.05cm. An empirical formula describing the relationship between the dispersing velocity and the mass ratio of explosive particle was obtained as the result of theoretical analysis. The simulation results demonstrated that the particles fly along the axissteadily, with little scattering and good directionality. The dispersing velocities derived from theoretical analysis were found to agree with the results of the numerical simulations, which suggested the availability of this investigation.Downloads
