摘　　要：利用Fluent软件的物质传输模型和湍流模型模拟了不同压力下天然气管道的泄漏扩散。通过对比分析模拟结果,得到了不同泄漏压力对天然气扩散的影响效果。模拟结果可为天然气泄漏事故的处理提供一定参考。The leakage and diffusion of natural gas due to pipeline failure under different pressures has been simulated by using species module and turbulence flow module of Fluent. Through comparison and analysis of the simulation results, the effect of different leak pressures on the diffusion of natural gas was obtained, which could provide guidance to some content for dealing with accidents of natural gas leakage due to pipeline failure.
