解釋
剖面阻力-
Proceed from the angle of energy and taking considerations on interference factor and drag of airfoil profile, a kind of new typed calculation method on the design of vane air foil was put forward according to the vortex aerodynamics model of the rotor of wind turbines with horizontal axis
摘要根據水平軸風力機轉子的渦流氣動模型，從能量的角度入手，考慮干涉因子和翼型阻力，提出了葉片翼型設計的一種新型計算方法。 -
The endplate change dramatically reduces the vortices created by the front wheels, while the reduced width of the main profile cuts drag, helping to boost top speed at the fast san marino circuit
側板的改變戲劇性地減少了輪胎所產生的渦流，而長度的縮短則可以降低阻力，幫助車輛在高速的聖馬利諾賽道提升極速。 -
Blade profile drag coefficient
槳葉剖面阻力系數 -
At the heart of slcad is a sophisticated three - dimensional engineering model. this model includes the terrain, the structures and all the wires. the model can be viewed in plan profile sheets. the slcad model is much more than just a picture or cad drawing since slcad understands the relationship between these elements. when you drag a structure off the current alignment slcad will update wire positions. the effects of this structure move will be instantly visible in the plan profile sheet view. in slcad you concentrate on designing your line instead of wasting your time drafting
有時控制尺寸會有所調整，有時節點板設計會變化一下。傳統繪圖時，面對修改，面對審圖人員發現的錯誤，繪圖人員往往只能夠手工一筆一劃地修改dwg圖形，工作量非常大。雖然有自動成圖軟體的支持，但是對待修改圖的工作，依賴自動成圖軟體重新從頭再生成一遍圖形既麻煩又可能帶來其它意想不到的問題。 -
Experimental study and numerical simulation on drag reduction of the underwater vehicle based on surface profile design
基於表面設計減阻的水下航行體模型實驗與數值分析 -
It is found that drag reduction occurs with adequate wavenumbers and grows with an increase of h. the mechanisms are revealed through variations of velocity profile and the decrease of wall shear stress
分析減阻機理是流速分佈曲線及近壁區速度梯度介於層流與湍流之間， h值增大引起壁面剪應力顯著下降。
