近年来，由于天然气管道泄漏而导致火灾、爆炸的风险，对群众的安全、企业财产和环境等造成极大的威胁，因此，通过分析管道的泄漏模型，制定相应的对策保障天然气管道系统的安全、可靠的运行是非常有意义的。本文利用FLUENT对天然气管道泄漏扩散规律迚行了数值模拟，得到了甲烷的扩散规律及浓度分布规律，为有效预测天然气泄漏扩散的影响范围提供了依据。

Inrecent years, due to the natural gas pipeline leak and cause a risk of fire, explosion, the safety of people, property and the environment, such as enterprise caused great threat, therefore, through the analysis of pipeline leakage model to develop appropriate measures to protect the security of natural gas pipeline system and reliable operation is very meaningful. In this paper, FLUENT for natural gas pipeline leak was simulated diffusion law, has been the proliferation of rules and distribution of methaneconcentration, provide a basis for predicting the scope of effective diffusion of gas leaks.
