摘　　要：阐述一种基于PIV的气体管道泄漏检测系统低成本构建方案,并通过该气体管道泄漏模型系统分析气体流量、管道泄漏孔径等关键参数对气体泄漏行为的影响,定量揭示流速分布变化规律。结果表明,不同泄漏孔径下,气体流量与最大流速呈正相关且拟合模型R^(2)值在0.97~0.99之间,拟合效果良好。This paper expounds a low-cost construction scheme for a gas pipeline leak detection system based on PIV,and analyzes the influence of key parameters such as gas flow rate and pipeline leak aperture on gas leak behavior through the gas pipeline leak model system,quantitatively revealing the variation law of flow velocity distribution.The results showed that there was a positive correlation between gas flow rate and maximum flow velocity under different leakage apertures,and the R^(2) value of the fitting model was between 0.97~0.99,indicating a good fitting effect.
