摘要
在对爆破烟尘源及其特征分析的基础上,对爆破烟尘行为进行了探讨,提出了粒子系统的概念,进而对爆破烟尘行为、爆破烟尘在大气中的扩散进行了深入研究。基于建立的气固两相流动方程,运用四阶Runge-Kutta差分迭代算法,对冲击及蘑菇云阶段的烟尘时实行为进行了模拟;对于扩散阶段,建立了复杂状态下的带修正的多点高斯扩散模式,运用Java 3D技术对爆破烟尘的扩散行为实现了时实模拟。最后,编制出了BSMS模拟软件。
On the basis of analyzing the blasting soot and its characters, the behavior of blasting soot is discussed, then, a conception of particle system is presented. The blasting soot＇s behavior and its diffusion in the air were researched. The two-phase flow mechanics and Runge-Kutta＇s four stages difference interation method were used to simulate blasting soot behaviors in impulsive and mushroom period. Then, a complicated Gauss model with modified in multi-point blasting was established by using Java 3D program language, and the behavior simulation of blasting soot was realized during the diffision stage. Finally, real-time simulation software named BSMS about soot behavior generated by blasting was formulated.
