Professor Bengt Sunden (Ph.D., thermodynamics and fluid mechanics, Chalmers University) is a Professor in the Energy Sciences Department at Lunds University, Sweden. He has served as the Head of the Department since 1995. Professor Sunden has taught both undergraduate and graduate students and supervised over 170 M.Sc. theses. His current areas of research include Enhancement of heat transfer in compact heat exchangers; Computational methods of convective flow and heat transfer (CFD) in complex narrow geometries; Combustion - related heat transfer; Gas turbine heat transfer; Evaporation and condensation in plate heat exchangers; thermal imaging techniques; PIV; Heat exchanger networks; Multiscale and multiphysics transport phenomena in fuel cells. The author of approximately 500 papers published in international journals, books and proceedings, Professor Sunden has also been a keynote speaker at several conferences and has been invited to lecture and contribute papers on numerous occasions. The editor of a number of books in his field and the author of three textbooks in English, Professor Sunden is also a reviewer for numerous international journals. He initiated and was the first editor-in-chief of the International Journal of Heat Exchangers and is currently associate editor of the ASME Journal of Thermal Science and Engineering Applications. He is also editor-in-chief for the WIT Press book series Developments in Heat Transfer and he serves on the editorial board of four other journals. A fellow of ASME, Professor Sunden served as associate editor of the prestigious ASME Journal of Heat Transfer from 2005-2008. Since 2007 he has been Western Regional editor of the Journal of Enhanced Heat Transfer. The recipient of several international awards, in 2006 Professor Sunden was appointed honorary professor of Xi'an Jiaotong University, China. Professor Sunden is a recipient of the 2011 ASME Heat Transfer Memorial Award.
