Simulated study of the blasting smog-dust movement on account of particle system

Based on the analysis of blasting smog-dust and its characters,the mathematical model of blasting smog-dust movement was established through mass flux,momentum flux,buoyancy flux and closed hypothesis.The shape of blasting smog-dust clouds in the states of impaction,mushroom cloud and diffusion movement was simulated on account of particle system.A program named BSMS was generated and the real-time simulation of blasting smog-dust movement was implemented.
