水面漂浮油层消波作用的分析与计算

Analysis and Calculation of Wave Damping by Oil Layer Floating on Water Surface

本文基于文献[6]中对两种半无限流体界面稳定性分析的思想,以海面上漂浮油层的油-水-气系统为研究对象,考虑流体粘性及界面张力的影响,在线性范围内对油—水界面波的阻尼率提出了一种分析方法.并通过数值计算,给出了界面波波长、油层厚度等因素对油水界面波阻尼率的影响.

This paper deels with the damping rate of interfacial wave between water and oil layer floating on it. Based on the assumption of linearity the effects of the wave lengths and oil-layer thickness on the damping rate is investigated. The results show that the damping rate increases with the increase of oil-layer thickness and decrease of the wave length.
