摘　　要：依游艇的分类,分别选择某66 ft过渡型游艇和25 ft滑行型游艇,应用数值模拟软件和经验估算方法分别计算其在不同工况下的阻力,包括各方法计算的阻力随体积弗汝德数的变化以及用计算流体软件XFlow计算的游艇在自由液面的速度场、涡流场和波形,对比发现,大隅三彦方法的计算结果比较接近数值模拟的结果,大隅三彦图谱法估算半滑行艇的阻力可行,用大隅三彦经验公式估算滑行艇的阻力比较可靠。According to the classification of the yachts,a 66 ft transition yacht and a 25 ft planning boat were selected respectively to calculate the resistance of the yachts under different working conditions,including the change of resistance with the volume Froude number,the velocity field diagram,the eddy current field diagram and the waveform diagram of the yachts near the free liquid surface calculated by computational fluid software XFlow.Comparison of the results showed that the result of the Daisumi Mihiro's map method is close to the result of numerical simulation.It is feasible to estimate the resistance of the semi-planning craft by the Daisumi Mihiro's map method,and it is more reliable to estimate the resistance of the planning craft by Daisumi Mihiro's empirical formula.
