时序反转法的畸形波水槽造波实验和演化特征
Wave-Making Experiment and Evolution Characteristics of Abnormal Wave Tank Based on Time Reversal Method
摘要
Abstract
Given the low nonlinearity and inefficiency of traditional dispersive focusing methods in genera-ting rogue waves,as well as the technical bottleneck of missing wave-making details in time-reversal methods,this study improved the wave-making logic of time-reversal methods and proposed a high-precision controllable rogue wave generation approach.By constructing a triple logical judgment system,an experimental generation method for rogue waves based on the Peregrine breather solution was established.Using this method,four types of freak waves with different carrier wave amplitudes were generated in a wave flume,showing good agreement with analytical solutions.The time-frequency characteristics,energy distribution,and spatiotemporal evolution of rogue waves were investigated through fast Fourier transform(FFT)and wavelet analysis.The results demon-strate that:1)Energy transfers occurred from fundamental frequency to higher frequencies during rogue wave;2)The generalized energy values during rogue wave events were more than twice those during carrier wave pe-riods;3)The convergence formation and divergence dissipation processes exhibited asymmetric characteristics,with slower convergence rates compared to dissipation speeds.关键词
