摘要
随着城镇燃气建设事业的蓬勃发展,城区管道泄露对环境及人员的威胁越来越引起人们的重视。本文针对湖北省荆州市楚源大道燃气管道,建立物理模型并利用商用CFD软件进行数值计算。计算得到不同环境下的组份分布情况,并分析了不同外界风速对气体泄漏过程的影响及其爆炸极限分布情况。
Along with the vigorous development of the town gas construction career, the threat of city pipeline leaks on the environment and personnels has attracted the attention of people.In this paper,Established physical model of Hubei chuyuan avenue gas pipeline in jingzhou prefecture and numerical calculated it by using commercial CFD software.Calculated the distribution of the components under different environment and analysised the effects of the outside different wind speed range and the distribution of the explosion limit.
