leakage-vortex

基本解釋

Breakdown of the leakage vortex happens at about 80%axial chord and makes the downstream flow more turbulent in the larger region.
在80%25弦長附近，泄漏渦發(fā)生破裂，導致更強、更大范圍的紊流脈動。
This paper presents an experimental investigation of the transportation of the rotor tip leakage vortex and the rotor wake in an axial compressor stator passage.
結(jié)果表明,轉(zhuǎn)子葉尖泄漏渦和轉(zhuǎn)子尾跡周期地掃過靜子通道尖區(qū),導致該區(qū)出現(xiàn)周期性的流動阻塞和脈動。
The result shows: short splitter has weak influence on the suction pressure distribution, leakage flux and the position leakage vortex rotated on the tip of principle blade.
結(jié)果表明：短弦長小葉片對大葉片吸力面負荷分布、泄漏量以及泄漏渦的產(chǎn)生位置的控制作用較弱；
Secondary traverse flow velocity vector plots show the scrapping of the tip leakage vortex from the suction surface of one blade across the blade pitch to the pressure surface of the adjacent blade.
數(shù)值和實驗結(jié)果均表明，端壁移動情況下間隙區(qū)域的二次流動特征是刮削泄漏渦的形成和發(fā)展。
The result shows that double leakage vortexes are the dominating flow behaviors in the rotor tip region.
結(jié)果顯示一次泄漏渦和二次泄漏渦是動葉頂部的主要流動特征。
