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

摘要: 在对爆破烟尘源及其特征分析的基础上,通过质量通量、动量通量、浮力通量分析,加之闭合假设,建立了描述爆破烟尘运动的数学模型,基于粒子系统对爆破烟尘的冲击运动、蘑菇云运动和扩散运动的烟尘云形状进行模拟研究,编制出BSMS模拟软件,实现了对爆破烟尘运动实时模拟.

Abstract: 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.
