| Abstract: | Along with vigorous development of town gas construction,the threat of city pipeline leakage on the environment and persons has attracted the attention of people.In this paper,aiming at Jingzhou Chuyuan avenue gas pipeline in Hubei,physical model of the pipeline leakage was established,and numerical calculation was carried out by using commercial CFD software.Through the calculation,the distribution of components under different environment was gained;effect of outside wind speed on the gas leakage was analyzed as well as the distribution of explosion limit. |
