摘要
本文对波浪在水流中传播时的底摩擦损失问题进行了研究。文中采用等效摩擦功的方法,对底摩擦应力做了线性化处理。并利用波浪作用通量守恒方程推得了波浪谱的传递关系式。此外,在实验室条件下,对在水流中传播的规则波和不规则波的沿程衰减做了实验测量,实验表明,文中建议的方法与实验结果很相近。
The wave attenuation during its propagation in current by bottom friction is discussed in this paper. By using the concept of the equivalent bottom energy loss, the bottom stress is linearized. Based on the principle of conservation of wave action flux, the equation for the calculation of wave spectra transformation in current is derived. Experiments for both regular and irregular waves for the measurement of wave dissipation were carried out by the authors It is indicated that the results by the authors' proposed method agree well with the model test data.
