Cokelet理论在波流计算中的应用

应用Ｃｏｋｅｌｅｔ方法，计算了波流共同作用下的极限波高和波浪的相对角频率． 计算表明：当水深不是太浅时．计算结果与Ｄａｌｒｙｍｐｌｅ计算的极限波高，以及线 性波理论计算的相对角频率是十分接近的；而当水深很浅时则有一定的出入。

Application of Cokelet Theory in Waves and Currents

So far Cokelet method is the most accurate method for solving wave problem. But the dimensionless factors and coordination system used in this method is not convenient for engineering application. In this paper, another series of dimensionless factors and a new coordination system are introduced. Based on Cokelet method, the maximum wave height and relative frequency of waves to currents are calculated. It has been found that when water depth is not very large, the maximum wave height calculated by Cokelet method is very close to the results by Stream Function theory and the relative angle frequency of waves to currents by Cokelet method is quite similar to that of linear wave theory. When water depth decreases, the differences between the Cokelet method and other theories increase. Some recommendations are also given which are useful for engineering application.
