天然气管道发生泄漏会造成一定的危险性,很有可能造成爆炸等危害性极大的事故.通过对泄漏气体危险边界的研究,可以确定天然气泄漏扩散形成的危险区域.本文通过利用Fluent模拟软件对泄漏时间、泄漏孔径和障碍物三种情况进行模拟分析,分析不同工况情况对天然气泄漏扩散的影响,为处理泄漏事故提供理论依据.%Leakage of natural gas pipeline will cause certain danger, likely to cause explosion and other serious accidents. By studying the dangerous boundary of gas leakage, it is possible to determine the dangerous area of gas leakage. In this paper, the influence of different operating conditions on the diffusion of natural gas leakage is analyzed by using Fluent simulation software to analyze the leakage time, leakage aperture and obstruction.
