Abstract

Abstract: Using the finite volume method, the three dimensional mathematical model of fluid-structure interaction was built in the soil as a kind of porous media around underground pipeline, by the FLUENT soft to numerically simulate the ground temperature change and the range of oil distribution in the soil and the earth's surface when oil pipeline leaked in different pressures. The simulation results show that the temperature field around pipeline was the same in different pressures. After leak, the temperature field around pipeline changed slowly, and the greater the pressure was and the more obvious the change of the temperature field was. When the pipeline pressure was 2 times of original pressure, the spread amount of oil in the soil was less than 2 times.

Key words: Underground pipeline, Different pressure, Leakage, Temperature field, Diffusion

摘要： 利用有限容积法建立埋地输油管道周围土壤多孔介质的三维流固耦合数学模型, 借助F LUENT软
件, 模拟了不同压力的埋地管道泄漏前后管道周围大地温度场的变化情况及油品在地下、地表的扩散情况。模拟结
果表明, 泄漏前不同压力的管道周围温度场分布相同; 泄漏后不同压力的管道周围温度场变化缓慢, 管道压力越大,
温度场变化越明显; 当管道压力变为原来压力的2倍时, 油品在地下的扩散量比原扩散量的2倍稍小一些。
