摘要

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.

Abstract

To rapidly recover the oil spill, the new method of solid-liquid dual dragging was proposed and its mechanism was studied. By using Navier-Stokes equation, the mathematical model which represented dual dragging acting on the intermediate oil layer from bottom water layer and top adhesion belt was established and the numerical simulation of oil layer movement under the condition of both different oil viscosity and adhesion dragging speed was carried out. Simulation results show that the oil spill recovery rate is improved significantly, and the effects of oil viscosity on the recovery rate is reduced, therefore various oil spill can be recovered rapidly by solid-liquid dual dragging.

Key words： oil spill; recovery; dual dragging
