摘要：         研究燃气管道的泄漏，目的在于定性和定量地分析评价泄漏可能带来的危害。基于ＦＬＵＥＮＴ软件，用ＧＡＭＢＩＴ建立三维泄漏模型，对含硫天然气管道泄漏及扩散进行了三维数值模拟。结果表明：硫化氢的存在增加燃气管道的泄漏危险区域；在自由扩散状态下，泄漏气体主要集中在泄漏口上部，且危险区域较小；当存在环境风时，泄漏危险区域向下风向下移，形成气体聚集区域，而上风向气体较少。可见，硫化氢和环境风的存在，使含硫天然气泄漏扩散的危险范围增大。

Abstract: The Study on leakage of gas pipeline is to analyze and evaluate qualitatively and quantificationally the possible hazards. Based on FLUENT software established 3D leakage models with GAMBIT and simulated The leakage and release of sulfur natural gas pipeline at the state of 3D.The results show that the danger zone is greatly increased because of the presence of hydrogen sulfide simultaneously, at the condition of free diffusion. The leaked gas is mainly stayed at the upper of leak hole and has minor hazard zone, at the condition of wind. The hazard zone moved to downwind zone and gas gathered zone was formed but the direction of the wind had much less gas. Therefore, at the process of sulfur natural gas pipeline the hydrogen sulfide and wind lead to the increase of danger zone. 
