wake drag 中文意思是什麼
wake drag
解釋
伴流阻力-
The wake survey cannot be used to measure the drag of stalled airfoil or of airfoils with flaps down.
尾流測量不能用來測量失連狀態下的冀型或襟翼偏轉后的翼型阻力。 -
According to the character of outer shape of modem buses, the numerical calculations are performed from the simplest shape - cuboid by using ansys / flotran software. first, the foreside of the cuboid is modified step by step in 17 models ( this is equal to the process of modification to the foreside of a bus ). second, the afterbody of the cuboid is modified step by step in 9 models to model flow wake at rear end and get the drag coefficients and lift coefficients in different aterbodies
在本文中，應用ansys flofan軟體，根據現代客車外形的特點，從最簡單的長方體開始進行數值模擬計算，首先對長方體的前部進行逐步改造（相當于對一個客車頭部進行改造的過程） ，這一步驟包括了17個模型；然後再對其尾部進行變化，以模擬客車后車體形狀對空氣阻力系數的影響，該步驟包括9個模型：最後給出兩種現代客車的數值模擬結果。 -
I would have had that smile to wake up to and those arms to snuggle in, and he would have had that support and person there to drag him away from the computer to take a few minutes for himself, to put his toes in the sand, and to enjoy a sunset
我清晨醒來享受微笑和懷抱，而他會擁有一個支援者，會把他從計算機前引開，讓他有幾分鐘善待自己，會把他的腳趾頭埋到沙里欣賞一下落日風景。 -
And the results of the wake length, separation angle, and drag or pressure coefficient for low reynolds number are excellent agreement with previous experimental and numerical results
得到的低雷諾數下的迴流長度、分離角、阻力系數、壓力系數和現有的試驗或數值結果相比，都能良好吻合。 -
The relationship between the non - dimensional drag coefficient of sma plate face and time is presented, and the pressure distribution on and around the sma plate surface as well as the karman vortex configuration in the wake at a certain time are given
給出了形狀記憶合金薄板表面的流體無量綱阻力系數隨時間的變化關系，同時給出了某一時刻薄板表面及其周邊的壓力分佈和薄板尾跡中的卡門渦街形態。
