摘要:: 针对河流穿越管道泄漏后油品在水中的迁移扩散问题，采用计算流体力学中的有限体积法，选取标准κ -ε 湍流模型，建立河流穿越管道小孔泄漏的数值仿真模型。模拟了柴油在水域中的迁移扩散过程，并分析比较不同泄漏孔径、泄漏速度和水流速度条件下的油品体积分数和扩散范围。研究结果表明：泄漏速度、泄漏孔径和水流速度不仅直接影响油品在水中的扩散轨迹及迁移方式，而且会改变油品在水中的体积分数和扩散范围，该研究可为建立河流穿越管道漏油应急预报系统提供理论参考。（图10，表1，参10）

Abstract:: Targeting at the diffusion of leaked oil for rivercrossing pipeline, finite volume method and k -ε turbulent flow model are chosen to build a numerical simulation model of small hole leakage of river crossing pipelines. The diffusion process of diesel in water is simulated. The volume fraction and diffusion range of diesel under different leak hole diameter,leaking velocity and flow velocity of water are analyzed and compared. The results show that leaking velocity, diameter of leak hole and flow velocity of water can not only directly affect the diffusion trajectory and migration manner of diesel in water, but also change the volume fraction and diffusion range of diesel in water. This research can provide a theoretical reference to the construction of emergency prediction system of leakage accident of river crossing pipeline. (10 Figures,1 Table, 10 References)
