1) curve-slide aerofoil's blade
弯掠组合翼型风机
2) skew swept airfoils
弯掠翼
3) variable-sweep wing
变掠型机翼<火>
4) forward-swept wings
前掠机翼
5) swept and curved blade
弯掠叶型
1.
The results show that,the swept and curved blade can reduce the pile of the low energy flow at corner,and restrain the flow separation,improving the flow at the corner and enhancing the overall performance of the blade.
运用NUMECA对某内外涵组合压气机进行数值模拟,为了减小内涵静子表面流动分离,提高其气动性能,在对其设计改型过程中,先后采用了直叶片、根部后掠和根部后掠尖部前掠三种叶型,数值模拟结果表明,弯掠叶型能减弱根尖部低能流体的堆积,抑制端壁角区的气流分离,使根尖部流动得到改善,从而提高其整体性能。
