| 摘 要： | 本文在作者另文数值模拟得到的三维海浪基础上 ,进一步分析给出了三维波峰长度、高度及方向角度等特征量的统计分布。发现考虑海浪的方向性质后波峰分布不再是均匀连续的 ;波峰的长度分布受方向函数影响 ,方向分布越宽 ,波峰的平均长度越短 ,波峰的方向角分布越宽 ;波峰高度和长度在波峰高度较小时有很大的相关性 ,而在波峰高度很大时无关

| Abstract: | This paper analyzes the statistical distribution of wave crest characteristics such as crest length, crest height, and directional angles based on numerical simulation of 3 D random waves. The results show that the distribution of wave crests is no longer uniform and continuous when wave directional information is considered. The distribution of crest lengths is greatly influenced by the directional function. The wider range of the directional distribution of wave energy is, the shorter the mean crest lengths and the wider the range of the distribution of crest directional angles are. The crest height and crest length show a high correlation while the crest heights are low and they become independent at great crest heights. |
