摘要: 针对天然气管道穿孔泄漏扩散问题,结合有限容积法,建立了天然气管道不同泄漏位置的CFD仿真
模型,分别对天然气管道上部、下部、迎风侧及背风侧等4种工况的泄漏扩散进行了数值模拟。研究结果表明,下部
泄漏比上部泄漏气体更贴近地面且不易扩散,且横向危险范围也比上部泄漏大30~70m;迎风侧泄漏与背风侧泄漏
情况相似,但迎风侧泄漏危险区域的纵剖面面积更大,更危险。应用数值方法模拟管道穿孔扩散问题,给出了不同
工况下的泄漏范围,为天然气管道泄漏的安全输送及安全抢修提供了理论依据。

Abstract: To study the diffusing of gas piercing leakage, finite volume method is used to establish CFD simulation model that detects different locations where gas pipes leak and four styles of diffusing, leakage of the upper, lower, windward and leeward side of the pipeline, were numerically simulated. According to the research, the leakage of lower is closer to the ground and diffuses less easily than the upper leakage, which has a 30~70 m larger dangerous area of cross range section. The leakage of windward side is similar to the leeward side, but the lengthwise section area of the former leakage is larger and more dangerous than the latter. And this simulation of leakage area provides theoretical base for safety transportation of gas and security maintenance of pipelines.
