Dr Lei Chai
Research Fellow

Elliott Jaques 087


Lei Chai has successfully completed his PhD at Beijing University of Technology in 2012 and then worked as a Lecturer at Chinese Academy of Sciences for 2 years and as a Postdoctoral Researcher Assistant at Queen Mary University of London for 3 years. Lei Chai has published over 50 scientific papers on experimental and numerical investigations on microscale heat transfer, thermal energy storage, compressed air energy storage, boiling and condensation, and supercritical fluid heat trasfer. Since June 2017, Lei Chai has become a Research Fellow at the RCUK national Centre for Sustainable Energy use in Food chains (CSEF), at Brunel University London. His research now focuses on CO2 heat exchangers and power and refrigeration systems.
