摘要： 利用仿真模拟软件, 对架空天然气管道泄漏扩散进行数值模拟, 对比分析了泄漏方向及风速对泄漏扩散过程的影响。结果表明, 地面附近下风向危险范围大, 上风向相对安全, 地势较高处相对安全; 向上喷射时近地面天然气危险范围较小, 迎风喷射和向下喷射时危险范围较大; 迎风喷射时风速对危险范围的影响小于向下喷射时
风速对危险范围的影响, 在静风及低风速下天然气泄漏扩散范围较大。研究结果可为架空天然气管道泄漏的应急疏散、 救援提供理论依据和参考。

Abstract: In reference to previous research, the simulation software to simulate overhead gas pipeline leakage diffusion in the flat areas was used and the effects of four different leakage directions and speed on leakage diffusion process were analyzed.The results showed that the risky range of upwind area was bigger than the downwind area near the ground, the higher ground was relatively safe.The risky range of upward natural gas jet was the smallest,the risky ranges of windward and downward jet were the greatest.The impact of wind speed on the risky range of windward jet was less than downward jet.Natural gas leakage in the condition of lower wind speed and calm wind spread wider.The results could be used for the emergency evacuation and rescue of overhead natural gas pipeline leakage in the future.

Key words: Natural gas pipeline, Leak, Numerical simulation, Jet direction, Wind speed.
