# On 3D Inverse Design of Centrifugal Compressor Impellers with Splitter Blades

Written by Prof. Mehrdad Zangeneh

## **What's inside?**

Centrifugal compressor impellers with splitters use identical blade shapes placed at mid-pitch. However, conventional design methodologies suggest that altering the pitchwise location of the splitter leading edge can enhance performance. In this paper, we develop a 3D inverse design method that designs full and splitter blades based on specified circulation distributions. We describe the selection of loading (derivative of circulation with respect to meridional distance) and stacking conditions to manage blade shape complexity.

 

> Two different generic impellers with varying splitter leading edge locations are designed, and their performance is compared to corresponding conventional designs using a 3D viscous code across design and off-design conditions.
