# Hydrodynamic Design of Pump Diffuser Using Inverse Design Method and CFD

Written by Prof. Mehrdad Zangeneh, University College London, and Akira Goto, Ebara Research Co Ltd.

## **What's inside?**

**A new approach to optimizing a pump diffuser is presented**, based on a three-dimensional inverse design method and a Computational Fluid Dynamics (CFD) technique.

The improvements in stage efficiency were confirmed experimentally over the corresponding conventional pump stage. The application of multi-color oil-film flow visualization confirmed that the large area of the corner separation was completely eliminated in the inverse design diffuser.

> The validity of this new design methodology, which directly controls 3-D pressure fields and secondary flows,** has already been confirmed for a wide range of diffuser pump specific speeds**. **Appreciable improvements in hydraulic performance have been confirmed experimentally** over conventional designs by using CFD based state-of-the-art approach.

### In this publication, you will:

1. **Discover** a new methodology to directly control 3D pressure fields and secondary flows;
2. **Understand** how the 3D inverse method can suppress corner separation by using fore loading at the hub;
3. **See** the optimization of the three-dimensional pressure fields and the flow behavior inside the flow passage.
