摘　　要：对油气管道泄漏时内部的动态特性进行研究,可以发现泄漏时管道流体状态的变化规律并对判断泄漏工况提供有效指导,更好地预测泄漏的影响。应用Fluent软件进行建模,对模型进行网格划分和仿真分析,模拟不同泄漏孔径的管道内部变化情况,研究发现随着泄漏孔径的增大,管道内的流体压力呈降低趋势,而其速度呈增长趋势,同时泄漏的质量流量也会变大。The study on the oil and gas pipeline’s internal leakage was implemented to show that,the change rule of fluids within the pipeline can effectively guide the judgment of leakage conditions and benefit the leakage impact prediction.Fluent software was adopted for modeling,meshing and simulation analysis of the model to simulate the internal changes of the pipeline with different leakage apertures.The study results showed that,with the increase of the leakage aperture,the fluid pressure in the pipeline decreased and its speed increased,meanwhile,the leaking mass flow also increased.
