压力扰动 meaning in Chinese
pressure disturbance
Examples
- A perturbation in pressure at the upstream end of the feed system could result in sizable oscillations in flow rate and chamber pressure .
供应系统上游端的压力扰动可导致相当的流量和室压振荡。 - A pressure disturbance cannot drive the energy release profile uniformly to the anti-node region to result in a sustained longitudinal wave .
压力扰动不可能驱使能量释放分布图移至波腹区域以产生持续的纵向波。 - In these experiments acoustic excitations were employed to play the role of the feedback of the upstream - propagating disturbances of pressure in the impinging shear flow
实验中，以声激励代替在撞击剪切流中向上游转播的压力扰动的反馈作用。 - Results show that restaggering ogv is more effective to reduce disturbance in integrated pylon case but with less effective in separated pylon case
分离式吊架情况下，对减小扰动的作用不明显；一体化式吊架情况下，通过适当调整出口导流叶片安装角可以有效地降低转子后的压力扰动，改善流场。 - The shearing layer is carried by the jet and the eddy is formed because of the instability and selective amplification of shearing layer which will propagate to the downstream . as the eddy impacts the impinging wall , a wave of pressure disturbance with certain frequency is induced . this wave then propagates to the upstream with high speed , and results in the overlap and amplification of the waves when the frequencies of them are close with each other
当前喷嘴流束中的不稳定扰动波在穿过腔内的剪切层时，剪切层对其有选择放大作用，形成涡环结构，剪切流动中涡环与碰撞壁撞击，在碰撞区域产生压力扰动波并向上游反射，在上游剪切层分离处诱发新的扰动的产生，当新扰动与原扰动匹配时，射流上游就被不断地受到周期性激励，腔内就产生流体自激振荡并在后喷嘴出口形成脉冲射流。
