The effect of reynolds number on rudder hydrodynamic performance is also analyzed. up to the stall angle the computed lift and drag agree well with measurements and other author ' s calculations, whereas stall angle, lift and drag beyond the stall angle are slightly under - predicted. the solver is used to investigate laminar and turbulent separated flows around a 6 : 1 prolate spheroid at high incidence angles and their effects on hydrodynamic forces
應用所開發的求解器，以naca0015翼型舵為算例計算了船舵在不同雷諾武漢理三;大學博士學位論文數下大舵角范圍內的三維粘性流場及水動力，成功地預報了舵的失速角和最大升力，並初步探討了雷諾數對舵水動力的影響;計算結果與現有試驗和計算數據比較，吻合程度相當好，初步檢驗和驗證了該求解器精確模擬粘性流動和計算水動力的能力。 -
The tension force, shear forces ( including pushing force, cutting force and friction force ), impulse force, hydrodynamic drag on the suction pipes, and the force resulted from the pressure difference, etc, are the main forces for detail discussion in this paper
詳細討論了主要作用力：在波浪補償器作用下的纜繩拉力、耙頭與海床間的土壤剪切力、作用在耙吸管上的水流阻力及由於壓力差在耙頭處產生的推動力等。 -
In this paper, the author analyses various form factors and shapes of a few hullform alternatives of a 2000 teu container, by use of the methods of experience, design charts, to estimate their performance ; adopting numerical methods to calculate their drag and effective horse power, studies the principal effects of both form - factor variations and hull shape change on their hydrodynamic performance, and other problems to be noticed in ship remoulding
本文主要通過對2000箱集裝箱船的幾個變形船型的主要參數和形狀進行分析，採用經驗法和圖譜方法對各變形船型作性能估算分析，並用數值方法計算各船型的阻力性能，初步探討船型參數、形狀改變對性能影響的主要方面，研究改型時應注意的問題。
