船形阻力
英文
form drag-
Standard process for model resistance test of displacement ships and its record form
一般排水量船模阻力試驗規程及結果的標準表達形式Chapter 4 computes the wave - making resistance, the 3d wave figure and its contour figure of wigley ship and makes satisfying results
第4章對wigley船型的線性興波阻力、不同弗氏數下的三維波形和等高線圖作了數值計算，也取得了令人滿意的結果。The radiation condition is satisfied numerically with collocation points shifting upstream. as applications of the method, flow around a 3 - d body, the wave pattern and wave resistance of a ship are solved. the encouraging numerical results are achieved
本文運用該方法計算了三維物體的繞流、興波波形和興波阻力，給出了wigley 、數學swath船型定常直航運動時的興波波形和興波阻力，其結果與實驗結果、理論結果進行了比較，結果比較令人滿意。In this respect, it tends to be an alternative of towing tank tests. the solution of 3d viscous flows around a ship in steady straightforward courses is capable of capturing more nearfield flow features than model tests and predicting viscous resistance with high accuracy, whilst for viscous flows around a ship in maneuvering motions such predictions are only in general good
三維船舶粘性流計算方法，具有準確捕捉船體周圍粘性流動細節包括船模試驗難以測量的流動形態的能力，已成功地應用於船舶快速性方面的阻力預報；在船舶操縱性方面，這類方法雖處于初始發展階段，但也已獲得重大進展，具有精確預報船舶操縱水動力的潛力。Increased radiation from the sun and occurrence of geomagnetic storms i. e. severe distortion of geomagnetic field of the earth may cause disturbances such as increases in density in the earth s upper atmosphere. these result in a greater drag on the movement of satellites and spacecraft, causing a slow - down or even a change in orbit
輻射的增加及地磁暴即地球磁場急速變形的出現，會導致地球上層大氣的擾動，例如空氣密度的上升，從而使衛星和太空船在航行時受到的阻力大增，航行速度因而減慢，甚至軌道亦會改變。Increased radiation from the sun and occurrence of geomagnetic storms ( i. e. severe distortion of geomagnetic field of the earth ) may cause disturbances such as increases in density in the earth s upper atmosphere. these result in a greater drag on the movement of satellites and spacecraft, causing a slow - down or even a change in orbit
輻射的增加及地磁暴（即地球磁場急速變形）的出現，會導致地球上層大氣的擾動，例如空氣密度的上升，從而使衛星和太空船在航行時受到的阻力大增，航行速度因而減慢，甚至軌道亦會改變。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。分享友人
