# Aerodynamic and Aeroacoustic Optimization of a Transonic Centrifugal Compressor

Written by Prof. Mehrdad Zangeneh and Dr. Peng Wang (Department of Mechanical Engineering, University College London).

## **What's inside?**

The **performance of transonic compressors** can be characterized aerodynamically and aeroacoustically. In this paper, the DLR SRV2 compressor without vaned diffusers and its redesigned version are studied. The redesign strategy utilized the **3D inverse design** and **CFD analysis**.

 

> Both compressors were analyzed in **ANSYS CFX 11**, and the computational results show that the predicted pressure-ratio and **efficiency of the original compressor have good agreement with experimental results**. The simulations have also revealed that the **redesigned one is superior at both design and off-design points at different rotating speeds**.

### In this publication, you will:

1. **See** the methodology to examine the aerodynamic and aeroacoustic performance of a transonic centrifugal compressor and its redesigned version.
2. **Understand **why the employed 3D inverse design methodology has provided a better solution in terms of the aerodynamic and partially aeroacoustic aspects.
3. **Discover **the advantage of using an optimization strategy that couples inverse design method and the current aeroacoustic model to redesign another transonic compressor with vaned diffusers.
