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.
