Background
Je-Chin Han is presently Distinguished Professor and holder of the Marcus C. Easterling Endowed Chair and Director of the Turbine Heat Transfer Laboratory at Texas A&M University. He was a R&D engineer at Ex-Cell-O Corporation in Michigan (1976-1980). Since 1980, Han has been a faculty member in the Department of Mechanical Engineering at Texas A&M University where he has conducted research and taught courses in thermodynamics, fluid mechanics, and heat transfer. In 1989, Han was promoted to Professor of Mechanical Engineering. In September 1991, he was named Halliburton Professor of Mechanical Engineering and then in January 1993 he was named the College of Engineering’s HTRI Endowed Professor. He was appointed Division Chair for the Thermal and Fluid Sciences Division of the Department of Mechanical Engineering from July 1993 to August 1998. Han was a Research Fellow at Wright-Patterson Air Force Base from May-August 1985. He took a sabbatical leave to NASA-Glenn Research Center and United Technologies - Pratt and Whitney Turbine Module Center from September 2000 to August 2001. In June 2001, Han was selected as the inaugural holder of the Marcus C. Easterling Chair Professor in Mechanical Engineering. In May 2006, Han was named Distinguished Professor of Texas A&M University.
Research
Han’s main research areas focus on advanced gas turbine heat transfer and cooling technology. He has worked on turbine blade cooling research since he was a graduate student at M.I.T. in the early 1970s. He is nationally and internationally known for his pioneering work in rib-turbulated internal cooling technology in the early 1980s. Since joining TAMU in 1980, he has worked on many turbine heat transfer cooling projects with a total funding of more than $7.0 million, including augmented internal cooling of turbine airfoils, rotating coolant passages heat transfer, rotating blade film cooling, unsteady high turbulence effects on turbine blade film cooling, combustor liner cooling, mini-scale heat transfer and turbine edge cooling (leading-edge, trailing-edge, platform, and blade tip regions) under engine flow conditions. Han’s research has been on aircraft propulsion, electricity generation, and industrial gas turbine applications funded by NSF, NASA-Lewis/Glenn, AFOSR, Wright-Patterson, the U.S. Army, the U.S. Navy, Textron-Lycoming, the State of Texas-ATP and ERAP, DOE-Advanced Gas Turbine Systems Research and DOE-University Turbine Systems Research, GE-Aircraft Engines and GE-R&D Center, Solar Turbines, United Technologies-Pratt & Whitney, Siemens-Westinghouse, and Honeywell Aerospace. During Han’s sabbatical leave with NASA-Glenn Research Center and United Technologies-Pratt & Whitney (9/1/00 - 8/31/01), he was involved in the UEET (Ultra Efficient Engine Technology) Program, which focused on the first rotor blade film-cooling and internal cooling designs with the goal of reducing cooling flow requirements in gas turbines and improving gas turbine durability and efficiency of newly developed super-cooled blades. Dr. Han has supervised more than 33 Ph.D., 23 M.S. students, and 15 Post-Doctoral Research Associates/Scholars. He served as editor, associate editor, or on editorial boards for 7 national and international journals. Han is the author or co-author of approximately 360 technical publications (including 180 refereed journal papers, 20 articles appearing in books, and 180 refereed conference papers). His publication has received more than 2,000 scientific citations according to the ISI Web of Science (http://isiknowledge.com, 2-3-07).
