Abstract

Abstract:

The areas that city gas pipelines distributed in always crowd with people and buildings, and once gas releases through damaged pipes, accidents would happen involving substantial economic losses and even victims amongst the population. Therefore, in order to quantify the hazards of city gas leak, different leakage and diffusion models were established according the characters of gas and the damage. The diffusion model of unsteady leakage of gas pipeline and the damaging and destroying areas were established. Based on the computational fluid dynamics(CFD) technique the diffusion range of leaked gas during accident of underground gas pipeline that caused by the third party damage was studied. According to the results, the dispersion of the leaked gas was obtained and provide the theory basis for safety operation of city gas pipelines.

Key words: Gas pipelines, Leakage , City , Leakage model , , Diffusion model , The third party damage , , Numerical simulation

摘要： 城镇燃气管道的分布区域人口及建筑众多,燃气管道一旦发生泄漏,将有可能造成重大的财产损失
甚至人员伤亡。因此,为了量化城镇燃气泄露危害,针对管道不同的破坏情况及气源建立了燃气泄漏各种源模型以
及扩散模型,并且建立了燃气管线动态泄漏扩散模型及伤害性危险范围。对第三方破坏所造成的城镇燃气管道泄
漏模型进行了模拟,采用CFD技术对管道泄漏燃气的扩散进行模拟研究,获得了泄漏气体的扩散数值模拟结果,为
城镇燃气管道安全运行提供了理论依据。
