非光滑叶片对叶栅流道内通道涡影响的实验研究

EXPERIMENTAL STUDY OF THE EFFECTS OF NONSMOOTH BLADES ON MSSAGE VORTEX

在低速平面叶栅风洞中对光滑叶片叶栅及三种非光滑叶片叶栅进行了实验研究，以研究 与光滑叶片相比，非光滑叶片对叶栅流道内通道涡发展变化的影响。实验结果表明，与光滑叶片相 比，非光滑叶片对叶栅流道内的通道涡有明显的影响，通道涡的位置沿节距方向移向流道中心处， 沿叶高方向不变，通道涡的强度有所减弱。分析了非光滑叶片的影响原因。

In the low speed plane cascade wind tunnel, the experiments for the cascades equipped with conventional smooth blades, three non-smooth blades were carried out to study the effects of non-smooth blades on the passage vortex. The experiment results show that using non-smooth blades can change the passage vortex.
