vortex lift 中文意思是什麼
vortex lift
解釋
旋渦引起的升力-
The results are compared with the cases in a single - layer fluid, showing that the density stratification can have a relative large effect on the drag and lift coefficients as well as the vortex shedding
計算受迫振蕩圓柱體的升力系數、阻力系數隨時間的演化曲線和圓柱體的尾渦分佈,以及圓柱體的受迫振蕩激發兩層流體內界面的擾動,並與均勻流體的情況進行了比較分析。 -
The resolute of numerical calculation indicates that, when re > 100, the karman vortex - street appeares, the pressure on the surface of the circle cylinder is pulsing ; when re < 1, back - flow is appeared ; when re = 10, the coefficient of lift is comparable with the theory in 0 < 9. 25
文中給出了雷諾數等於10時的升力系數計算結果並與理論值進行了對比,在一定范圍內與理論值有可比性。 -
He is confident that, someday, with his crafts maneuverability and energy - saving vortex generator ( a device that creates lift much like dragonfly wings ) you wont need airplanes anymore
他相信,總有一天,與他船的機動、節能渦發生器(顯示器製造電梯很像蜻蜓翅膀)你不用飛機了
