摘要
基于随机波浪的Longuet-Higgins模型,给出了4种模拟畸形波的数值模型:相位调制模型(部分组成波初相位相同模型和调制相位角范围模型),相位调制加聚焦模型,随机波加瞬态波模型以及改进的相位调制模型。简要介绍了各模型的优缺点。其中,随机波加瞬态波模型和改进的相位调制模型最优,实现了畸形波的定时定点和定量生成,为实验室模拟畸形波、研究畸形波的能量以及对结构物的作用奠定了基础。
Based on the Longuet-Higgins wave model theory,four numerical models for generation of freak waves were presented including phase modulation model （some wave components with the same phase model and different phase interval models）,phase modulation and wave focusing model,random wave and transient wave model,a modified phase modulation model.Certain advantages and disadvantages of the models were briefly introduced.Among the models,the random wave and transient wave model and the modified phase modulation model are the best numerical methods, they can make the freak wave generation at a certain time and place, and also change the size of freak wave slightly.Based on the models,it is possible to generate freak waves in laboratory and do further investigation of the freak waves energy and interactions with structures.
