# Three-Dimensional Design of a High Speed Radial-Inflow Turbine by a Novel Design Method

Written by Prof. M. Zangeneh (Mechanical Engineerin Department, University College London).

## **What's inside?**

This paper is concerned with the **design of a high speed, 5 inch diameter radial-inflow turbine for medium-sized diesel engine turbocharger application**. The turbine was designed by a newly developed fully three-dimensional compressible inverse design method, in which the blade shapes are computed for a specified distribution of rVθ.

 

> The performance of the new impeller was measured and then compared with three other impellers, one conventional and two experimental. The new impeller performed substantially better than all the baseline turbines and showed a **5% improvement** in the total-to-static efficiency over the conventional turbine.

### In this publication, you will:

1. **Learn **how the objectives of high speed and a good compromise were met (5% improvement in the total-to-static efficiency over the conventional turbine).
2. **Understand **the challenge how improving the performance of radial-inflow turbines by designing blades with non-radial blade filaments.
3. **Discover** how engineers can achieve better efficiency design using the 3D inverse design method.
