Biography

John Longley is an Associate Professor in the Department of Engineering at the University of Cambridge specializing in turbomachinery and high-speed compressors. His research focuses on flow disturbances, particularly the stability of multi-stage axial flow compressors and the development and design types of gas turbines. He has conducted significant research on the breakdown mechanisms of flowfields, contributing valuable experimental observations and theoretical model comparisons through various projects, including BRITE/EURAM funded initiatives. Longley's work extends to advanced modeling techniques for high-speed compressors, where he addresses the complexities introduced by radial flow variations. Additionally, he investigates mainstream stator-shroud leakage flow interaction, which poses engineering challenges such as drum heating and reduced blade row efficiency in aeroengine compressors. His projects are driven by practical needs and supported by significant funding, including from EPSRC and Rolls-Royce, involving large-scale experimental and computational studies to enhance compressor efficiency and reliability.
