摘　　要：为进一步解决天然气管道泄露而引起的重大安全事故及隐患,在对天然气泄露扩散机理研究的基础上;基于FLUENT软件构建了天然气管道泄露数值模拟仿真模型,重点对管道压力、泄露方式等对天然气扩散的影响机理展开研究;最后,以可调谐半导体激光吸收光谱(TDLAS)实验系统为核心对天然气管道的泄露进行检测,实现了对天然气管道泄漏点的准确判定。In order to further solve the major safety accidents and hidden dangers caused by natural gas pipeline leakage,based on the study of natural gas leakage and diffusion mechanism;Based on FLUENT software,the numerical simulation model of natural gas pipeline leakage is established,and the influence mechanism of pipeline pressure and leakage mode on natural gas diffusion is studied,based on TDLAS experimental system,the leakage of natural gas pipeline is detected,and the leakage point of natural gas pipeline is determined accurately.
