摘要
本文研究了深水中波浪流对斯托克斯波的影响。分别利用波浪剖面函数的三阶、四阶和五阶近似和确定的波流速度表达式,表明在海洋表面的波流速度更强,但随着深度的增加,波流速度呈指数递减。分析还表明,随着波浪陡度的增大,波流速度增大。进一步推导出四阶和五阶波流速度大小相同;由此可见,随着阶数的增加,斯托克斯波中有关波流速度的解具有收敛性。JONAMP Vol. 11 2007: pp. 363-368
This study considers the impact of wave - current on Stokes waves in deep water. Using separately, the third, fourth and fifth order approximations of wave profile functions respectively and the determined expressions for wave – current speed , it is shown that the wave - current speed is more intense on the surface of the ocean, but however, the intensity reduces exponentially downwards with the depth. The present analysis also suggests that the wave – current speed increases with increase in wave steepness. It is further deduced that the wave- current speed is the same in magnitude for both fourth and fifth order; thus, showing the convergence of solutions concerning wave - current speed in Stokes waves as the order increases.
