Stirling Convertor Regenerators

Mounir Ibrahim is professor of mechanical engineering at Cleveland State University (CSU), Ohio. Ibrahim has been involved in research on fluid flow and heat transfer in different areas and applications, including heat transfer in gas turbines, gas turbine combustors, Stirling engines, and Stirling regenerator design using microfacbrication techniques, to name a few. He has more than 35 years of administrative, academic, research, and industrial experience. Ibrahim is a Fellow of the American Society of Mechanical Engineers (ASME) and Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA). He has been the chair of the ASME K-14 (Heat Transfer in Gas Turbines) Committee (July 2006 to June 2008). He also chaired the Mechanical Engineering Department at CSU from March 1998 to June 2002. He was a visiting scholar at Oxford University in 2008, and at the University of Minnesota, Minneapolis, in 2002. He has been awarded more than $5 million externally funded research and has supervised more than 60 masters and doctoral students. He has published more than 100 publications in prestigious journals and conference proceedings. Ibrahim has two patents: High-Temperature, Non-Catalytic, Infrared Heater, U.S. Patent #6368102 and U.S. Patent #6612835. Roy Tew was an analytical research engineer for more than 46 years at the National Aeronautics and Space Administration (NASA) Glenn Research Center. He worked on space-power projects, with particular emphasis on Stirling power-convertor analysis, until his retirement in January 2009. In these areas, he also acted as grant and contract monitor for efforts including research into Stirling thermodynamic loss understanding, Stirling regenerator research and development, and development of Stirling multidimensional modeling codes. While employed at NASA, Tew was an author or coauthor on 29 NASA reports and other published papers. He earned degrees in physics (B.S. from the University of Alabama), engineering science (M.S. from Toledo University, Ohio), and mechanical engineering (Dr.Eng. from Cleveland State University). He is a member of the American Society of Mechanical Engineers (ASME) and the American Institute of Aeronautics and Astronautics (AIAA). He was an Ohio Registered Professional Engineer until he let his license expire after retirement. Since retirement, Dr. Tew has been working with Mounir Ibrahim of Cleveland State University to prepare this book. During the fall semester of 2010, he taught a graduate course in energy conversion at Cleveland State University (his first experience in teaching a course). Although retired from NASA Glenn, he currently works there as a Distinguished Research Associate, a part-time, volunteer position.
