Compact Design of Diffuser Pumps Using Three-Dimensional Inverse Design Method

Written by Akira GOTO and Kosuke ASHIHARA, Ebara Research Co., Ltd., Takaki SAKURAI and Sumio SAITO, Ebara Corporation.

What's inside?

A novel approach for designing diffuser pumps is presented based on a three-dimensional inverse design method and the Computational Fluid Dynamics (CFD) technique.

Both impeller and diffuser blade shapes were computed for specified circulation or blade loading distributions, which can be optimized for a specific design requirement.


Compact Design of Diffuser Pumps

The two examples clearly show that the new design approach based on the 3D inverse design method and the CFD enables high
efficiency, high suction performance, and much more compact design of diffuser pump stages. The validity of this new design methodology has already been confirmed for a wide range of diffuser pump specific speeds.

In this publication, you will:

  1. Discover the design guidelines and examples for high suction performance pumps;
  2. Understand how this novel approach will enable turbomachinery designers to quickly develop diffuser pumps;
  3. See the advantage of using the 3D inverse design method for designing high performing pumps.
