Professor John Chew is a faculty member at the University of Surrey's School of Mechanical Engineering Sciences, holding the position of Professor of Mechanical Engineering. His research focuses on fluid dynamics, heat transfer, and aero-elasticity with applications in turbomachinery and seal systems. He serves as Editor of the Journal of Mechanical Engineering Science and has chaired ASME Turbo Expo 2016. His work emphasizes advanced CFD techniques like LES and WMLES for predicting flow in rotating disc cavities, turbine rim seals, and brush seals. Key contributions include studies on centrifugal buoyancy effects, inertial/acoustic wave dynamics in seals, and swirl reduction strategies in brush seals. He has collaborated extensively on experimental and numerical validations of seal performance and thermal management in turbine systems.
Research Interests: Professor Chew's expertise spans computational fluid dynamics (CFD), turbomachinery internal air systems, and seal design. His studies address challenges in rotating systems such as ingestion mechanisms, heat transfer optimization, and unsteady flow phenomena. Recent work includes parametric studies of grooved front plates for brush seals, wall-modeled LES for turbine rim sealing, and Ekman layer effects in buoyancy-driven convection.
Awards and Recognition: While no specific awards are listed, his sustained contributions to the field have earned him roles in academic leadership and peer review, including membership in the EPSRC College Peer Review College and the Aerodynamics National Technical Committee.
Advising and Grants: Although specific student advisees are not explicitly listed, his research group likely supports PhD candidates in turbomachinery and CFD modeling. His projects have explored funded topics such as cooled cooling air systems, scroll expander aerodynamics, and thermal contact resistance in turbine components.
Labs and Teams: His work is conducted within Surrey's aerothermal test facilities, emphasizing experimental validation of numerical models for industrial applications in gas turbines and hybrid propulsion systems.
