摘　　要：基于计算流体力学(CFD)对非合作目标条件下甲烷遥测路径进行分析,结合一维视线积分浓度表征模型,开展不同风速、不同泄漏位置工况下甲烷逸散数值模拟研究,探究不同扫描方案下,甲烷视线积分浓度值变化规律,获得油气场站激光检测最优方案,与实际检测路径进行光路匹配。研究结果表明:在不同泄漏位置与不同风速条件下,光路水平距离为5 m的扫描方案能够实现油气场站泄漏气体的快速扫描与报警;随着泄漏位置与检测器水平距离增大,风速增强,光路水平距离为5 m的扫描方案在报警时间方面比其他方案优越性更明显。Based on Computational fluid dynamics(CFD),the methane telemetry path under the condition of non-cooperative targets was analyzed.Combined with the one-dimensional line of sight integrated concentration characterization model,a numerical simulation study of methane emission under different wind speeds and different leakage locations was carried out to explore the change law of methane integrate concentration value under different scanning schemes,to obtain the optimal scheme for laser detection of oil and gas stations,and match the optical path with the actual detection path.The research results indicated that a scanning scheme with a horizontal distance of 5 m in the optical path could achieve rapid scanning and alarm of leaked gas in oil and gas field stations under different leakage locations and wind speed conditions.As the horizontal distance between the leak location and the detector increased,the wind speed increased.The scanning scheme with a horizontal distance of 5 m in the optical path had more obvious advantages in alarm time compared to other schemes.
