Heat Transfer

Greg Nellis is an Associate Professor of Mechanical Engineering at the University of Wisconsin, Madison. Professor Nellis received his MS and PhD at the Massachusetts Institute of Technology. Professor Nellis is a member of ASHRAE, ASME, IIR and CSA and carries out applied research that is related to energy systems with a focus on refrigeration technology. Professor Nellis has published more than 40 journal papers. Professor Nellis's focus has been on graduate and undergraduate education and he has received the Polygon and Pi Tau Sigma awards for excellence in teaching. Professor Klein is the Bascom Ouweneel Professor of Mechanical Engineering at the University of Wisconsin, Madison. He has been on the faculty at Wisconsin since 1977. He is associated with the Solar Energy Laboratory and has been involved in many studies of solar and other types of energy systems. He is the author or co-author of more than 150 publications relating to the analysis of energy systems. Professor Klein's current research interests are in solar energy systems and applied thermodynamics and heat transfer. In addition, he is also actively involved in the development of engineering computer tools for both instruction and research. He is the primary author of a modular simulation program (TRNSYS), a solar energy system design program (F-CHART), a finite element heat transfer program (FEHT) and a general engineering equation solving program (EES). Professor Klein is a Fellow of the American Society of Mechanical Engineers (ASME); the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE); and the American Solar Energy Society (ASES).
