摘要
以线性波浪理论为基础,推导了随机波条件下有限水深波浪的功率表达式,对现场实测的波功率进行统计研究。根据两个测站的波功率计算及波功率与特征波高和特征周期之间关系的分析,发现有限水深的随机波波功率受水域深度影响,并且某位置处的波功率与特征波高和特征周期之间可能存在确定的系数关系。
Usually wave energy resource needs to be evaluated before its exploitation and is estimated through wave power level. The expression of wave power for a random wave with finite water depth is deduced from the linear wave theory, and wave power of field data is investigated. Through the computation of wave powers from two stations and the discussion of the relation of their wave powers to characteristic wave heights and periods, it can be found that the wave powers of random waves for the finite water depth are affected by water depth, and the wave powers at some station may have a certain quantity relation to characteristic wave heights and periods.
