...年Hawthorn根据涡线迁移理论首次给出了经典的二次 流旋涡模型，如图1．1所示，他将叶栅的二次流旋涡分为通道涡（Passage Vortex）、出口丝线涡（TrailingFilamentVortex）和出口脱落涡（Trailing ShedVortex）三部分，这种旋涡的计算和分类方法都是在无粘假设下...

The fence vortices are related to the flow between fence and endwall,and the suction surface fence’s height on the blade surface. The interaction between fence vortex and passage vortex is different with the fence location height along blade.
翼刀涡的形成、发展和变化受翼刀-端壁间气流流动情况和翼刀安装高度的影响,翼刀涡与通道涡的相互作用因翼刀安装高度而异。
