船體線形對貨櫃船而言非常重要，其不只影響船體阻力，更會影響螺槳入流，進而牽動推進效率與螺槳空化現象。但改善船體線形之前，必須有一套可行方法進行阻力計算，船體阻力包含了黏性阻力與興波阻力。針對興波阻力，本論文即提出一有效方法進行貨櫃船自推狀態下非黏性阻力計算。以一貨櫃船船型SR138為計算範例。計算結果顯示：自推時之船體阻力增加皆為螺槳之吸力所引起，自推時船體阻力增加、螺槳的興波非常顯著，與10 m船模實驗值相當吻合。

For the container ships, the ship resistance, propeller inflow and propulsive efficiency are deeply dominated by the hull lines. In order to improve the hull lines, the ship resistances including the viscous and wave-making resistances should be correctly predicted. The main object of this paper is to develop a method to solve the wave-making resistance of the container ship under the self-propulsion condition. A container ship model, SR138, is taken as the computing sample. The computing results show the propeller suction effect increased the hull resistance remarkably at the self-propulsion condition, and the wave amplitudes are obvious. The numerical results make good agreement with the measured data.
