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.
