测量和估算湍应力的主要方法之一是利用潮波支配方程。根据杭州湾的实际情况,我们采用了三种方法,得到了较一致的结果。第一种方法直接利用动量方程。第二种方法是将动量方程在一个海区上积分,得出应力项在全域上的总体估计值。第三种方法是利用能量方程,得出拖曳系数估计值。本文所用的第一种方法是Bowden等及wolf所用方法的一个直接的推广;第三种方法的应用最早可追溯到Taylor;第二种方法则是这里首次提出的。
One of the main methods of measuring and estimating turbulent stress is the use of tidal wave governing equations. According to the actual situation in Hangzhou Bay, we have adopted three methods, obtained more consistent results. The first method directly uses the momentum equation. The second method integrates the momentum equation over a sea area to obtain a global estimate of stress terms over the entire area. The third method is to use the energy equation to derive the drag coefficient estimate. The first method used in this paper is a direct extension of the method used by Bowden et al. And wolf. The third method is first applied to Taylor. The second one is presented here for the first time.
