- This paper presents a completely new approach to control aerodynamic surge in centrifugal compressors, which has not been seen previously. It achieved an unprecedented 58% improvement in the stable operating range of a high-pressure transonic compressor. The paper clearly presented the fundamental aerodynamic mechanisms underlying the improvements and provided measurements from one of the world’s most sophisticated compressor test rigs to verify the performance improvement. ABB, which is the technology and market leader in turbochargers for large marine and locomotive engines, adopted the outcomes and patented (WO2019034740A1) the method and design guidelines (daniel.rusch@ch.abb.com).
