| 摘 要： | 本文基于五阶Stokes规则波理论,提出了一种快速求解深海极限波浪运动特性的数学模型.研究中,按照上跨零点和下跨零点的方法由计算或实测的极限波浪波面时间历程确定包含极限波峰或波谷的相邻两个周期的平均值为五阶Stokes规则波的波浪周期,然后根据极限波峰或波谷值反推确定波浪入射波幅.通过与已有的数值结果和实验数据对比,验证了本文所建立的数值模型可以快速准确的计算出极限波浪下的速度场,相比其他模型,更适合于工程应用.

| Abstract: | Based on the fifth-order Stokes regular wave theory,a simplified model for extreme-wave kinematics in deep sea was developed.In this model,from the wave records the average of two neighboring wave periods for the extreme crest or trough was defined as the period of the Stokes wave by the up and down zero-crossing methods.Then the input wave amplitude was deduced by substituting the wave period and extreme crest or trough into the expression for the fifth-order Stokes wave elevation.Thus the corresponding fo... |
