针对含不同硫化氢浓度天然气的泄漏扩散问题，采用 Fluent 软件进行了相应的数值模拟。模拟结果表明：泄漏气体在泄漏喷射最大轴中心处泄漏的速度最大，离轴越远速度降低越快；随着硫化氢浓度增大，气体泄漏速度降低到大小相同时所需射流高度将减小；泄漏气体中硫化氢浓度越大，其扩散危险区域范围就越大。通过数值模拟得出的相关规律对实际安全生产和应急救援提供了一定的理论依据。

In view of the leakage and diffusion problems of sulfur-containing natural gas, the corresponding numerical simulation was performed by using Fluent software. The results show that, the velocity of leakage gas on the real axis is the largest; it decreases faster as it gets further from the hub of the axis. As the concentration of hydrogen sulfide in natural gas increases, the velocity of leakage gas reduces to the same size with a smaller jet height. The higher the concentration of hydrogen sulfide, the larger the range of dangerous area spreads. The results of numerical simulation provide certain theoretical basis for safety production and emergency rescue.
