| 摘 要： | 近水面水翼的兴波由升力线的自由面兴波来表达,船体的兴波考虑升力线兴波的干扰影响,三维时域格林函数法用于船体的兴波分析计算.以Wigley船型为数值计算例,考虑近水面水翼的影响,分别对单体船和双体船进行了船舶兴波计算研究,提供了兴波波形和兴波阻力的计算结果.以系列60船型为数值计算例,把计算的结果与发表的有关结果进行对比,具有较好的吻合.本文还对船舶自由表面兴波波形进行了时域数值仿真.

| Abstract: | The wavemaking of the hydrofoil is represented by the lifting line.The ship wavemaking incorporated with the hydrofoil is computed by 3-D Green function method in time domain.Wigley hull form with hydrofoil is employed as numerical example for the computation of mono-hull ship and catamaran.Some computed results are presented.The Series 60 hull form is also used as numerical example and the computed results are compared with published data.The ship wavemaking on the free surface is simulated in time domain. |
