What's inside?
In this paper, for the first time, a set of guide-lines are presented for the systematic design of mixed-flow and centrifugal compressors and pumps with suppressed secondary flows and a uniform exit flow field.
The paper describes the shape of the optimum pressure distribution for the suppression of secondary flows in the impeller with reference to classical secondary flow theory.
The results show consistent suppression of secondary flows in all cases. The overall performance of the stage with the inverse designed impeller with suppressed secondary flows was found to be 5% higher than the conventional impeller at the peak efficiency point. Exit flow traverse results at the impeller exit indicate a more uniform exit flow than that measyred at the exit from the conventional impeller.
In this publication, you will:
- Discover a fast and reliable 3D Inverse Design method that plays an important role in developing designs of mixed-flow and centrifugal compressors and pumps with suppressed secondary flows;
- Understand the process to develop a set of guide-lines for the suppression of the secondary flows on radial and mixed-flow impeller blades;
- See how turbomachinery designers will be able to design a new generation of mixed-flow and radial turbomachines.
