氯气瞬时泄漏浓度演化过程模拟研究

The Simulation Study on the Evolution Process of Chlorine Instantaneous Leakage Concentration

以高斯烟团模型为基础,建立氯气瞬时泄漏气体扩散浓度分布数值模型,利用MATLAB软件求解该模型,对求解结果以可视化图形进行数值模拟,分别模拟了大气稳定度为A、C、E,风速为1.5,2.5,3.5 m/s,泄漏时间为30,60,90,120,150,180 s的演化结果,其仿真结果很好的显示了氯气瞬时泄漏浓度动态演化过程,为评估氯气泄漏事故风险,划分应急疏散范围提供了数据支持。

Based on the Gauss puff model,the diffusion concentration distribution model of chlorine instantaneous leakage gas is established,and the model is simulated by MATLAB softwar. The evolution results of atmospheric stability of A,C,E,wind speed of 1. 5,2. 5,3. 5 m/s,leakage time of 30,60,90,120,150,180 s are simulated respectively. The simulation results show the dynamic evolution of the leakage process,which can provide data support for emergency management of chlorine leakage.
