摘要
在文献 [1 ]研究的基础上 ,提出了一种新的基于奇点法的变叶片高度环列叶栅逆命题设计方法。此方法利用叶片给定表面速度分布求解叶片形线。数值验证显示出本方法可有效地克服文献 [1 ]中方法存在的叶片形线上法向速度振荡现象 。
A new inverse method to design circular cascades with varying blade height was developed on the basis of the singularity method [1] .The method solves blade contour from a given surface velocity distribution.Numerical simulation shows that the method can effectively avoids the fluctuation phenomenon of the normal velocity distribution on the blade contour occurred in Ref.[1],it is thus more convenient to use in engineering application.
