suction vortex 中文意思是什麼
suction vortex
解釋
吸入渦-
Its peculiarity is that the vortex pair formed on the ejection stroke can ? move far enough under the self - induced velocity, so the vortex pair is sucked into the cavity of the actuator during the suction stroke
這種流動的特點是：在作動器的「吐出」行程，其出口產生的旋渦對還來不及向下游遷移便進入了作動器的「吸入」行程，重新進入作動器腔體。 -
Based on an engineering background, through numerical simulation of the flow field in the hp turbine of the energy efficient engine ( e3 ), the article research the unsteady flow in a transonic turbine stage, the unsteady phenomena in the stage include the shockwave, wake, shedding vortex, endwall vortex, passage vortex and leakage vortex, etc. there are two shockwaves generated on the vane the tailing edge, one on suction side is named moving shockwave, and name another on pressure side steady shockwave
本文首先對于研究的意義和國內外研究的現狀做了簡要的介紹，再從某工程背景出發，通過對e3發動機高壓渦輪內流場的數值模擬，研究了干涉的周期性的問題，以及渦輪級內常見的非定常現象：激波、尾跡、脫落渦、根腳渦、通道渦、漏流渦。導向器尾緣會出現兩道激波，在吸力面的激波可稱為「運動」激波，壓力面的激波可稱為「定常」激波。 -
Abstract : this paper uses the topology theory to analyze the surface flow spectrums of straight, positively curved and negatively curved cascades with relative tip clearances of 0. 023 and 0. 036, finds apparent differences of topology and vortex structures in the blade tip and the suction side wall corner of single type of cascade with this two clearances, and studies the mechanism of the difference formation as well as their effects on the energy loss
文摘:應用拓撲原理分析了葉頂相對間隙為0 . 023和0 . 036的渦輪直葉柵和正、反彎葉柵的壁面流譜，發現在兩種間隙下同類葉柵的拓撲與旋渦結構在葉頂和吸力面壁角明顯不同，探討了差別形成的機理及其對能量損失的影響
