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

摘要: 在對爆破煙塵源及其特征分析的基礎上,通過質量通量、動量通量、浮力通量分析,加之閉合假設,建立了描述爆破煙塵運動的數學模型,基于粒子系統對爆破煙塵的沖擊運動、蘑菇云運動和擴散運動的煙塵云形狀進行模擬研究,編制出BSMS模擬軟件,實現了對爆破煙塵運動實時模擬.

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.
