摘要
该文在二维波浪水槽中进行了不规则波与逆流相互作用的实验;分析了逆流的存在对不规则波列中出现的畸形态的影响。结果表明逆流会增加畸形波出现的概率;畸形波的波形以高波峰为主,能占总畸形波的85%以上。畸形波波峰前端相对陡峭,后端较平缓;然而不同逆流流速下畸形波的平均波形差异不明显,与新波模型吻合较好;逆流对畸形波的平均波面影响很小,说明新波模型可以用来描述逆流存在下的畸形波波形。
Experiments of wave-current interactions in irregular waves are conducted in a 2 D flume.Characteristics of rogue wave shapes under the effect of opposing current in irregular waves are analyzed.The results show that the probability of occurrence of rogue waves will increase with the opposing current.Rogue waves with higher crest are in majority and can reach up to 85%of the whole.The averaged non-dimensional rogue waves present a steep front and a gentle rear.However,there is no remarkable difference between averaged rogue wave profiles with different opposing current velocities and wave shapes coincide well with the New Wave model.Current velocity has little impact on the averaged rogue wave profiles;the conclusions above demonstrate that the New Wave model is also valid under the opposing current effect.
