摘要

船舶波型是海洋流体力学和水波学领域中一个引人注目的研究课题。在纯重力波理论中,出现在下游的横波和发散波组成的船波型被限制在与航迹对称的半角扇形内。然而,当考虑到表面张力时,波型会发生很大的变化,特别是在低平移速度下。除了毛细波的最小速度cmin = 0.23 m/s之外,还有一个临界速度cdiv = 0.45 m/s与发散波的消失有关。本文研究了稳定平移源产生的波形,并用渐近分析得到的峰线对其进行了检验。

Capillary-gravity ship wave patterns

Ship wave pattern is a fascinating research topic in the fields of marine hydrodynamics and water waves. Within the pure-gravity wave theory, the ship wave pattern composed of transverse waves and divergent waves appearing on the downstream is confined within a sector symmetrical about the ship track with a half-angle . However, when the surface tension is accounted for, the wave pattern is greatly modified especially at a low translating speed. Besides the minimum speed of capillary waves cmin = 0.23 m/s below which waves cannot be generated, there is another critical speed cdiv = 0.45 m/s associated with the disappearance of divergent waves. In the present paper, the wave patterns created by a steadily translating source are studied, and they are examined with the crestlines obtained from the asymptotic analysis.
