| 摘 要： | 基于MIKE21 SW海浪模式,建立非结构网格下的瓯江口二维、双向波流耦合数学模型,对该海区波流共同存在下的二维流场进行了数值模拟,计算结果与实测数据吻合良好,且优于未耦合的结果,比较分析表明：考虑潮流作用大大改善了波高和周期的计算结果,使之更接近观测结果；波浪对潮位的影响较小,对流速的影响较大,其中落潮憩息时刻,波浪对流速的影响最大.

| Abstract: | Based on MIKE21 SW wave model, a two-dimensional, bi-directional wave-current coupling mathematical model with unstructured triangular grid was set up, and applied to the numerical simulation on tidal flow under wave-current interaction in the Oujiang Estuary. The results of coupled model agreed with the measured data well, and better than the uncoupled. Accord- ing to the simulation, the wave field and tidal flow of the uncoupled and coupled model were compared. The study showed that the current effect greatly improve the results of the calculation of wave height and wave period, and closer the observations. The wave is mainly reflected in the current velocity instead of the current level. |
