燃气管道泄漏及扩散发展研究

Research on Gas Pipeline Leakage and Diffusion Development

文中总结了国内外燃气管道泄漏扩散研究技术进展,归纳了燃气管道泄漏扩散数值模拟软件和经典计算模型;从地面障碍物、燃气浓度变化、不同地质条件、危险区域半径等不同层面分析燃气扩散在土壤中的影响;通过建立不同场景的计算模型,探讨风速、建筑物间距、不稳定扩散等不同条件时燃气扩散对大气环境的影响,对实际应用和研究工作具有借鉴意义。

This paper summarized the development of gas pipeline leakage diffusion research technology at home and abroad,and summarized the numerical simulation software and classical computing model of gas pipeline leakage diffusion. The influence of gas diffusion on soil was analyzed from the ground obstacles,the change of gas concentration,different geological conditions and the radius of the dangerous region. The effects of wind speed,building spacing,unstable diffusion and other conditions on the atmospheric environment were discussed. It was of reference significance for the practical application and research.
