| 摘 要： | 采用有限容积法建立埋地管道周围土壤中油水两相流的三维流动传质数学模型, 借助C F D软件分别模拟了冬季管道不同位置发生泄漏后周围土壤温度场的变化及油品在土壤中的扩散分布情况。模拟结果表明, 泄漏前, 管道周围形成稳定温度场。泄漏后, 随管道泄漏位置变化, 大地温度场变化不同, 油品在土壤中呈不同形状扩散分布。

| Abstract: | The three dimensional flow and mass transfer mathematical model of oil water flow in the soil around underground pipeline is built using the finite volume methodo. The ground temperature change in different locations is numerical simulated by the CFD software when oil pipeline leaks in winter and the range of oil distribution in the soil. The simulation results show that there is a stable temperature field around the pipe before leak, while the changed of temperature fields and the oil distributions are different under three conditions after leak. |
