天然气管道泄漏规律及实验研究

Nature Gas Pipeline Leakage Law and Experimental Research

该文以管道气体泄漏与扩散测试装置为试验平台,设计试验,通过研究泄漏过程中管道气体压力、流量的变化趋势,总结气体泄漏规律,重点讨论了对泄漏速率的影响。将理论计算数据与试验数据结合分析,用origin对理论公式进行修正,力求理论模型的实用性和通用性,为泄漏过程的模拟和风险评价提供理论基础和数据支持。

In this paper, with the liquid leakage and diffusion test device as the test platform, by designing the experiment to study the trends of pressure and flow rate of gas during leakage, to sum up with the law of gas leakage, focus on the impact on leakage rate. Compared with the theoretical calculations and experimental data, and corrected the theoretical formula with origin, to make the theoretical model more practical and versatile, and provide a theoretical basis and data support for simulation and risk assessment of the leakage process.
