摘要
基于随机波浪的Longuet-Higgins模型,在相位调制方法的基础上提出考虑航速影响的改进方法,调制部分组成波的初相位,实现舰船在顶浪航行情况下定时定点遭遇畸形波。同时,保持随机波列的频谱特性,并利用计算流体力学(Computational Fluid Dynamics,CFD)数值波浪水池验证该模型的有效性,为舰船遭遇畸形波的数值模拟及相关耐波性研究提供一种新途径。
A freak head wave train generation model based on the Longuet-Higgins wave model is proposed,which modulates the initial phases of certain component waves according to the speed of the ship to make the ship encounter freak waves at given time and position.The modulation does not change the spectral characteristics of the random wave train.The model is verified by means of the Computational Fluid Dynamics（CFD） numerical wave tank.This study demonstrates a novel way of the numerical simulation of ships encountering freak wave and the research on sea-keeping capability of ships.
