为快速回收海面溢油,提出固液双重拖带回收新方法并分析其工作机理.应用Navier-Stokes方程,建立表征固液双重拖带过程中底部水层及顶部黏附带对中间油层双重拖带作用的数学模型,并对油层在不同黏度和黏附拖带速度条件下的运动状态进行数值模拟.结果表明:应用固液双重拖带回收方法可以明显提高溢油的回收速度,并降低了溢油黏度对回收速度的影响,能够实现对水面各种油品溢油的快速回收.
In order to recover the oil spill from the sea quickly, a new method of double-dragging solid-liquid recovery was proposed and its working mechanism was analyzed.A mathematical model was established to describe the double drag effect of the bottom water layer and the top adhesion zone on the middle reservoir during the double-dragging of solid-liquid by Navier-Stokes equation Model and the numerical simulation of the movement of the reservoir under different viscosities and adhering towing velocities.The results show that the recovery rate of oil spillage can be significantly increased by using the solid-liquid dual towing recovery method, and the effect of oil viscosity on the recovery rate Impact, to achieve the rapid recovery of various oil spill on the surface of the water.
