Conjugated Heat Transfer

Clean Energy Processes (CEP) Laboratory 

The Clean Energy Processes (CEP) Laboratory is based in the Department of Chemical Engineering at Imperial College London. Currently, approximately 35 members (post-doctoral, doctoral and master students) are at the core of this research laboratory. Our mission is to conduct significant research in applied thermodynamics, heat and mass transfer, and energy efficiency in power generation, heat and/or cooling provision. Our projects are in relation with industry and in collaboration with international research centres and universities.
