The Advanced Thermofluids and Heat Transfer Research Laboratory (TF-LAB) is a state-of-the-art research laboratory, conducting fundamental and applied research in the areas of heat transfer, thermodynamics, and fluid mechanics. Our mission is to advance the state of energy transport, exchange and conversion technologies to help address the world’s energy challenges. It is a hub for cutting edge experimental research and has extensive collaborations with international academic and industrial partners.
Dr. Roger Kempers — Director
Dr. Roger Kempers earned his BEng and MASc degrees in Mechanical Engineering from McMaster University and a Ph.D. in Mechanical Engineering from Trinity College Dublin, Ireland. Prior to joining Lassonde he was a Distinguished Member of Technical Staff at Nokia (formerly Alcatel-Lucent) where he led the R&D of advanced thermal management technologies for telecommunications hardware and as Research Engineer at Lucent Technologies, Bell Labs Ireland where his activities ranged from fundamental research to technology development, licensing and product integration. His research interests lie primarily in the area thermal-fluid sciences with a multi-disciplined nature and is geared towards the advancement of heat transport, exchange and conversion technologies to help address the world’s energy challenges.
Dr. Hossam Sadek — Deputy Director
Dr. Hossam Sadek is currently an Assistant Lecturer in Lassonde School of Engineering. He received his Masters and PhD degrees from McMaster University, Department of Mechanical Engineering, in 2004 and 2009 respectively. During his Masters and PhD studies, he investigated the effect of high voltages on two phase flow and heat transfer. This included designing an advanced experimental facility to both visualize and obtain quantitative data for tube side convective condensation under the application of high voltage electric fields. In 2010, he won “MITACS Industrial Accelerate PhD Fellowship” and started his research as a Post-Doctoral Fellow at McMaster University. The focus of the research was developing a low-cost, reliable and environmentally friendly thermal electric waste heat recovery system using thermoelectric generators. This was accomplished through numerical and mechanistic modelling and experimental testing.
Dr. Sadek teaching experience include teaching courses such as Thermodynamics, Mechanics of Materials, Dynamics, Heat transfer, Thermodynamics of energy systems, Mechanical engineering as a profession, Fluid mechanics, and Engineering ethics.
Dr. Sadek is the Graduate attribute lead for Mechanical engineering in Lassonde School of Engineering at York University. His responsibilities include identifying and developing outcomes-based assessment opportunities, strategic plans, and a Faculty level Graduate Attribute Assessment Framework.
Dr. Frédéric J. Lesage — Associate Member
Dr. Frédéric J. Lesage received his PhD in Mechanical Engineering from McMaster University and his MSc in Mathematics from the Université de Montréal. He is currently an Associate Professor with the department of Computer Science and Engineering at the University of Quebec in Outaouais. Professor Lesage supervises graduate and undergraduate students who conduct research in the fields of thermoelectricity, phase change phenomenon, boiling, mathematical modelling and sustainable energy conversion technologies.
