单词

adverse pressure gradient

释义

adverse pressure gradient

简明释义

逆压梯度：在流体动力学中，逆压梯度是指静压在流动方向上增加的压力梯度。数学上表示为dP/dx > 0，其中x为正方向上的流动。

网络释义

1
?逆压梯度
形成逆压梯度(adverse pressure gradient),引发钝体后端的边界层分离(boundary layer separation),流体回流(flow circulation)和尾流(wake);而且显著的改
2
?逆向压力梯度
... adverse device 抗G力设备 adverse pressure gradient 逆向压力梯度 adverse suit 抗G衣 ...
3
?反向压力梯度
... adverse factor 有害因素，不利因素 adverse pressure gradient 反向压力梯度；逆压梯度 adverse wind 逆风 ...
4
?力梯度
...况下，压力随时间的改变使得微扩散器内流向 (streamwise)的流速在达可能最大值之前即受到逆压 力梯度(adverse pressure gradient)的影响而减速。当频率越高，流向的可达最高流速越低，使得净流率随之降低。

短语

1
adverse and favorable pressure gradient
逆与顺压梯度

双语例句

1
The results indicate that passive control technique can reduce peak Mach number on the surface of the airfoil and reduce the adverse pressure gradient, shock is also weakened.
结果表明，被动控制使得沿模型表面的马赫数峰值及过压力梯度明显减小，激波减弱。
2
It is shown that the "damping" effect mainly exists in the zone of 0.5d from the impingement wall, and there are positive as well as adverse pressure gradient in the radial direction.
表明壁面的“阻尼”影响主要集中在近壁面0 . 5 D以内，在径向上流动既有顺压梯度，又有逆压梯度。
3
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。
