摘要 考虑了均匀剪切流场中强非线性界面波,建立了基于任意水深处速度而不是通常所用的平均速度为速度变量的模型,分析了其色散关系,并求得了各层速度的二阶渐近解和界面内波波面位移的二阶Stokes解,揭示了波流之间的非线性相互作用和界面波解之间的非线性相互作用。 Strongly nonlinear interracial waves of a finite amplitude with uniform shear flows are considered, a new model is derived using the velocities at arbitrary distances from the still water level as the velocity variables instead of the commonly used depth-averaged velocities. Dispersion relations are analyzed, and the second-order asymptotic solutions of the velocities and the second-order Stokes solutions of the associated elevations of the interracial waves are presented.
