Yann Bartosiewicz obtained his PhD in mechanical engineering from U. of Sherbrooke, Canada in 2003. After a position of research scientist at Natural Ressources Canada, he joined UCL in september 2005 as assistant professor. Since 2013 he is associate professor at UCL in the division of thermodynamics and fluid mechanics (TFL) which he lead between 2012-2016. His teaching duties include thermodynamics, thermal cycles and nuclear thermal-hydraulics. He is also an academic member of the Belgian Nuclear Education Network (BNEN) which he chaired between 2012-2016.
His research interest covers numerical simulation and experiment in thermodynamic, fluid mechanics and heat transfer for applications in energy systems and nuclear thermal-hydraulics.
For energy systems his research focusses on the investigation of supersonic ejectors to be used in waste heat recovery technologies as well as two-phase ejectors to be used in heat pumps. Those investigations are carried out at the component scale by as well as at the system scale. In both cas a balance is achieved between numerical simulations (CFD, system modeling) and experiments (local flow measurement/visualization within an ejector and full system experiment). In this field the collaborations includes Natural ressources Canada, University of Sherbrooke, Georgia Institute of Technology, University of Firenze, EDF (Electricité De France), Polish academy of sciences.
For nuclear thermal-hydraulics, the research is essentially conducted by numerical simulation. The main research topic concerning GENII/GENIII reactors is the simulation of two-phase choking occurring during the flashing of a liquid (application to a Loss of Coolant Accident) other two-phase flows situation related to safety. For future reactors (GENIV) the research is focussed on the simulation of turbulent heat transfer in liquid metals under different conditions; this includes direct numerical simulations (DNS), Large-Eddy Simulation (LES) and Reynolds Averaged Simulation (RANS). This research in thermal-hydraulics is essentially achieved through the participation in EU projects with many collaborators (EDF, CEA, NRG, SCK•CEN, VKI, etc.). More information ...

Miltiadis Papalexandris received an MSc degree in Naval Architecture & Marine Engineering from the National Technical University of Athens and MSc and PhD degrees in Aeronautics from the California Institute of Technology (Caltech). Soon after the completion of his PhD, he joined the Engineering Staff of NASA's Jet Propulsion Laboratory. While at NASA, he worked mainly on thermal control and optical modeling of space telescopes, including the James Webb Space Telescope (JWST) and the Laser Interferometry Space Antenna (LISA). In 2002 he became a member of the academic personnel (faculty) at UCL where he remains until now. He is the recipient of the William Balhaus Dissertation Prize of Caltech, NASA's Space Act Award, and the NOVA Award of Excellence of NASA. Prof. Papalexandris is an Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA).
The research activities of his group lie primarily on the fields of Theoretical and Computational Fluid Dynamics with particular emphasis on the fundamentals of multi-phase flows, complex fluids, and reacting flows. These activities cover: i) development of mathematical models for the flows of interest, ii) algorithm development and implementation for these models, iii) software verification and validation, and iv) detailed numerical studies and simulations via high performance computing.

Grégoire Winckelmans obtained a mechanical engineer degree from UCL (1983), a postgraduate degree in aeronautics and aerospace from the von Karman Institute (VKI, 1984), a M.S. degree (1985) and a Ph.D. degree (1989) in aeronautics from the California Institute of Technology (Caltech). He was senior scientist at STD Research Corp. until 1992, then postdoc at Caltech until 1993, then assistant professor at U. of Sherbrooke. He joined UCL in 1996 and is full professor since 2007.
