Hydrodynamic Wave Characteristics of Wind Wave Groups of Finite Amplitude
摘要
Hydrodynamic wave characteristics, such as waveform, hydrodynamic pressure field and velocity field, in non-regular groups of large-scale waves under the conditions of rough sea are described analytically. These expressions are derived through solution of a nonlinear boundary-value problem of the water-wave theory correct to the fifth order in the wave steepness by the multi-scale technique. In the general case, apart from non-linearity and non-regularity of waves, the three-dimensionality of the wave pattern and the prescribed surface pressure of the wind are taken into account. In the special case of the plane free wave groups, the approximate relations, appropriate for evaluation of the influence of the wind waves on the ships and the marine structures, are obtained. The asymptotic of the periodic progressive Stokes waves is considered as well.
