管道水下溢油运动特征二维模型试验研究

2D flume experimental study on the movement characteristics of oil spill from pipeline under water

为了解管道水下溢油的运动过程和特征,在室内水槽开展了二维溢油模型试验。通过试验观测溢油从水下上升至水面的运动过程和形态,并对溢油的上升时间、代表点处油粒子平均运动速度、溢油扩散宽度等特征与溢油初始溢出速度、水流流速的关系进行分析,试验结果可为水下溢油的运动轨迹及扩散数值模拟研究提供参考。

In order to understand the movement process and characteristics of oil spill in submarine pipeline,a two-dimensional oil spill model test was carried out in the flume.The movement process and shape of oil spill from underwater to water surface were observed through experiments.The relationship between the characteristics of oil spill such as rising time,average movement speed of representative oil particles and oil spill diffusion width with initial spillage speed and flow velocity were analyzed.The experimental results can provide reference for trajectory and diffusion numerical simulation of underwater oil spill.
