摘要:
以多点泄漏埋地输油管道为研究对象，建立土壤多孔介质中油水两相流动传热耦合模型，基于相似理论对管道泄漏计算区域进行缩放。利用CFD 软件Fluent 6.3 模拟埋地输油管道多点泄漏情况下地表温度场的特征以及多个泄漏点之间的相互影响，结果表明：满足一定条件的对流现象A、B具有传热和流动的相似性；泄漏点轴向距离为3 m 时，泄漏介质之间的相互影响较大，地表温度场的
泄漏区域呈不规则椭圆形；多点泄漏情况下地表温度场分布明显，在模拟条件下3 h 内地表温差达到10 K。

Abstract:
Taking the underground oil pipeline with multiple-point leak as a research object，the oil-water two-phase flow coupled heat
transfer model in the soil of porous medium is established and computational domain of pipeline leak is zoomed based on the
similarity theory. The features of soil surface temperature field for underground oil pipeline with multiple-point leak and their
inter-influence among different leak points are simulated by Fluent 6.3，CFD software. Results show that convection phenomena
A and B satisfying certain conditions are similar in heat transfer and flow. When axial distance between the leak points is 3 m，
the inter-influence between leak medium is great and leak domain of soil surface temperature field appears an irregular elliptic
shape. Soil surface temperature field with multiple-point leak distributes obviously and soil surface temperature difference can
reach 10 K within 3 hr under simulation conditions.
