... This paper presents the design method of the special-shaped centrifugal impeller based on the streamline curvature method. Some conclusions described in this article will be thoroughly analyzed and demonstrated in the second part. The second part mainly involves case analysis and numerical simulation...

... of controlling the peak value of some local data after the optimization, a local optimization strategy is proposed to make the method achieve better results. In the optimization, the streamline curvature method is used to perform the iterative calculation of the aerodynamic parameters of the S2 flow surface...
