Dr. C.-J. John Tam has more than 20 years of experience in Computational Fluid Dynamics (CFD) development and applications. From 1998-2014, he was involved in the research and development of scramjet engines at the Air Force Research Laboratory/Aerospace Systems Directorate in Wright-Patterson AFB, OH. He performed numerical simulations on different components of the engine to provide a better understanding of the flow physics, thus to design more efficient scramjet engines. In addition, he had validated various turbulence models, large eddy simulations, and chemistry kinetic models for reacting flows, and compared the numerical results with experimental data. In 2014, Dr. Tam joined Air Force Research Laboratory/Directed Energy Directorate at Kirtland AFB, NM. His research emphasizes on the flow physics around optical turrets using numerical simulations. Dr. Tam is an associate fellow of AIAA, and the author of numerous papers, journal articles, and technical presentations. He has served as a reviewer for many technical journals. He taught both undergraduate- and graduate- level classes in the Department of Mechanical and Materials Engineering at Wright State University (WSU) for 13 years, as an adjunct associate professor, and was nominated for the Excellence in Teaching Award for Adjunct Faculty for the 2006-2007, 2009-2010, and 2010-2011 academic years at WSU. In addition, he was inducted as an Eminent Engineer by Tau Beta Pi in 2010.
