将垂向考察区域分为波谷以下部分、波谷至平均水面部分以及平均水面以上部分,应用线性波理论,分段推求波浪剩余动量流沿水深分布函数.建立任意波向角时波浪剩余动量流各分量的计算表达式,给出深水及浅水条件下的渐近表达式,探研波浪剩余动量流的垂向分布情况.取波向角为30°分别计算深水、过渡水深及浅水条件下波浪剩余动量流的垂向分布.结果表明:波浪剩余动量流各分量沿水深并非均匀分布,而且各分量分布情况不尽相同;从波面到海底,存在反向变化的现象;浅水条件下,波谷以下部分所占比例相当可观.计算成果与实测资料和研究分析结果是一致的
The vertical investigation area is divided into the following troughs, troughs to the average water surface and above the average water surface, linear wave theory is applied to segment the remaining momentum momentum along the water depth distribution function. When the arbitrary azimuth angle is established, Asymptotic expressions in deepwater and shallow water are given, and the vertical distribution of residual momentum flow is explored.When the wave angle is 30 °, the residuals of deepwater, transitional depth and shallow water are calculated respectively The vertical distribution of momentum flow.The results show that: the components of the residual momentum stream are not evenly distributed along the water depth, and the distribution of each component is not the same; from the wave surface to the sea floor, there is a phenomenon of reverse change; Under shallow water conditions, The proportion is quite considerable.The calculation results are consistent with the measured data and the research and analysis results
