Transport Phenomena in Fires

Dr. Mohammed Faghri is known around the world for his work in Computational Fluid Dynamics and for his experimental research on fluid flow and heat transfer in microscale devices. He has published over 200 articles in the journals of thermal sciences, including the ASME Journal of Heat Transfer, Numerical Heat Transfer and International Journal of Heat and Mass Transfer. Dr. Faghri is the author or editor of six books on heat exchangers, modeling of thermal processes, heat and fluid flow in microscale and nanoscale structures, heat transfer in gas turbines, modeling and simulation of turbulent heat transfer, and transport phenomena in fuel cells. He has been on the editorial boards of four journals (Journal of Heat Transfer Research, International Journal of Heat Exchangers, Int. J. of Dynamics of Fluids, International Journal of Science and Technology and the ASME Journal of Heat Transfer). He is the recipient of the 2004 ASME Heat Transfer Memorial Award (the most prestigious national award in the field of heat transfer), a Fellow of ASME and was selected as the Jubilee (150th Anniversary) Professor at the Chalmers University and Wenner-Gren Foundation Fellow at Lund Institute of Technology, both in Sweden. His sponsored research has been under the auspices of NSF, NASA, the US Army, IBM and Ford Motor Company. His research interests include microfluidics experiments and Direct Simulation Monte Carlo in micro-channels and solidification and melting in low gravity. He is currently the principal investigator of a NASA research grant for 460K on Phase Change in Low and Jittering Gravity Environment and the principal investigator and the project director of 2.37 million dollars NSF research grant for five years starting 2005 on Micro-fluidic Technology and Applications. Bengt Sunden has held positions at Chalmers University, Sweden as Research Associate, Docent and University lecturer. In 1992 he was appointed Professor of Heat Transfer at Lund University, Sweden, where he has taught undergraduate and graduate courses in heat and mass transfer, fluid mechanics, and numerical flow simulation and has supervised more than 135 masters' theses, 25 licentiate of Engineering theses, and21 doctoral theses. His research topics are: Enhancement of heat transfer in compact heat exchangers; numerical methods of convective flow and heat transfer in complex narrow geometries; combustion - related heat transfer; thermal imaging techniques; heat exchanger networks; and heat and mass transfer topics. He has had approximately 300 papers published in well-recognized journals, books and proceedings and has delivered several invited lectures and papers. He has been editor of thirteen books published by international publishers, is involved with referee work for than twentyfive international journals, and is the editor-in-chief of the International Journal of Heat Exchangers and the for a book series Developments in Heat Transfer. In addition, he is in the editorial board for another four journals. Professor Sunden is a fellow of ASMEand currently serves as associate editor of the prestigeous ASME Journal of Heat Transfer.
