有毒气体泄漏绕障碍物扩散的安全性分析

Safety Analysis of Toxic Gas Leakage and Spreading around Barrier

介绍了用FLUENT软件数值模拟有毒气体泄漏绕障碍物扩散的方法,并根据伤害区域的划分对障碍物附近的安全性进行分析。基于FLUENT模拟三维瞬态流动的原理,选用标准双方程湍流模型,对有毒气体扩散的不同时段障碍物附近质量分数及安全性分别进行考察,从而归纳出有毒气体绕障碍物扩散及伤害区域分布的一般规律。

A method of simulating toxic gas leakage and spreading around barrier using FLUENT software was introduced, and the safety around barrier was analyzed in according to regional harm division. Based on the FLUENT simulation principle of three-dimensional transient flow and using the standard turbulence model, the mass ration of toxic gases and safety at different time phases around barrier was studied. The general rules of toxic gases pervasion and harmful area distribution were summarized.
