非光滑叶片对叶栅出口损失分布影响的实验研究

An Experimental Study on Effect of Unsmoothed Blade on Cascade Exit Loss Distribution

在低速平面叶栅风洞中对光滑叶片叶栅及3 种非光滑叶片叶栅进行了实验研究,主要是研究非光滑叶片对叶栅出口损失分布特性的影响。实验结果表明,采用非光滑叶片改变了叶栅出口损失的分布,减少了叶栅出口能量损失。相对于光滑叶片叶栅,3 种非光滑叶片中叶栅损失减少量最多约16.5% ,最少约9.1%

The cascades equipped with conventional smooth blades and three unsmoothed blades were investigaled experimentally in a low speed plane cascade wind tunnel to study the effects of unsmoothed blades on the exit loss distributions.The experiment results show that the unsmoothed blades can change the exit loss distributions and reduce the exit blade losses by 9 1%～16 5%.
