有限空间的甲烷泄漏模拟

Methane Leak Simulation in Finite Space

甲烷气体意外泄漏扩散时,容易造成人员伤亡,破坏环境。采用Fluent软件模拟有限空间的甲烷气体泄露,建立计算模型,对不同位置发生的气体泄漏进行模拟计算,分析甲烷的泄漏口位置、障碍物位置和泄露时间的影响,并得出有限空间内甲烷易于聚集的区域和甲烷不易聚集的区域,为甲烷报警器的安装和发生泄漏时的应急处理提供了理论依据。

When methane gas accidentally leaks and diffuses,it is easy to cause casualties and damage the environment.Fluent software was used to simulate methane gas leakage in a limited space.Related model was established and gas leakage was simulated.The methane leakage was analyzed from the impact of methane leak location,obstacle location and leakage time.The methane accumulation area and the area where methane is not easy to accumulate was in a limited space were obtained.The results would provide a theoretical basis for the installation of methane alarms and emergency treatment in case of leakage.
