摘　　要：为提高掺氢天然气管道危险介质检测效率,以流体力学为基础,进行不同工况下危险介质激光检测路径设置分析,并在不同环境风速下对危险介质流体力学进行仿真研究。研究结果表明:随着风速的不断增大,泄漏口与激光器间隔距离变宽,激光距离5 m时的扫描策略优势更明显。For purpose of improving the detection efficiency of dangerous medium in hydrogen-doped natural gas pipeline,having the fluid dynamics based to analyze laser detection path’s setting for hazardous medium under different working conditions was implemented,including simulation study of the fluid dynamics of hazardous medium at different environmental wind speeds.The results show that,with the continuous increase of wind speed,the interval distance between the leak and the laser increases and the scanning strategy with laser distance of 5 m has obvious advantages.
