摘要

同时调制周期和振幅的控制信号被微调并馈入一个波瓣产生异常波。采用无网格光滑粒子流体力学方法预测最大波峰的位置和振幅。dualspphysics软件输出的时间序列在BSHC耐波盆地进行了实验验证。实验数据与模拟结果吻合较好。

Numerical and Experimental Generation of Freak Waves

Control signals with simultaneous modulation of periods and amplitudes were finetuned and fed to a wave flap for a generation of freak waves. The meshless Smoothed Particle Hydrodynamics method was used to predict the location and the amplitude of the maximum wave crest. The time series output from the DualSPHysics software was validated experimentally at the BSHC seakeeping wave basin. The experimental data is in good agreement with the simulations.
