About

Background

Dr Qiang Zhang received his Ph.D. in Mechanical Engineering from the University of Utah in 2005 and held a Research Assistant Professorship at the University of Utah in 2006. From late 2006 to2010, he was a research staff in the Osney Thermo-Fluids Laboratory at the University of Oxford (Rolls-Royce Heat Transfer and Aerodynamics University Technology Centre), where his work mainly focused on transonic turbine blade aero-thermodynamics. Dr. Zhang has been an Associate Professor at the University of Michigan & Shanghai Jiao Tong University Joint Institute since 2010. From 2014, Dr. Zhang returned to Uk and became a full time faculty member with City University London.

Dr. Zhang’s research interests include gas turbine heat transfer and cooling, aerodynamics, conjugate heat transfer, experimental techniques, CFD simulation and validation. He has published 25 journal papers (J. Turmocach., Physics of Fluids, AIAA, etc.), and held two US/UK/EU patents. He currently serves the ASME IGTI Heat Transfer committee (K-14 gas turbine committee for ASME heat transfer division).
