adverse pressure gradient

常见例句

双语例句

• In zero pressure gradient flow, this local momentum loss is Minost an additive constant quantity. On the other hand, adverse pressure gradient results in amplification of this momentum loss.
  在零压力梯度下，这个局部的动量损失几乎是一个附加的常量，而逆压梯度则会扩大这种动量损失。
• The high head produced by the impeller means high adverse pressure gradient within blade passage and because of this the flow often separates from the blade surfaces even at the design point.
  低比转速泵的高扬程决定了叶片流道内逆压梯度比较高，这种压力分布使得水流易于在叶片表面脱流分离，这一现象甚至在泵的设计点也难以避免。
• The results indicated that three-dimensional open separation exists due to the cross flow around the afterbody, thicker boundary layer and the stronger adverse pressure gradient on the lower surface.
  结果表明，上翘后体引起横向流动，使横向逆压梯度增大、下表面边界层增厚，导致后体出现三维开式分离流动；
