Abstract: Nonequilibrium describes a physical process that is not able to reach a well-defined equilibrium state within a time scale relevant to a system.
For gas flow around a hypersonic vehicle, nonequilibrium energy transfer and chemistry of the molecules directly affect the heat transfer to the vehicle. The thermal response of the material comprising the hypersonic vehicle Thermal Protection System (TPS) is analyzed using strong coupling to the external nonequilibrium flow. The coupling is performed through detailed modeling of the surface energy processes.
Several examples are presented of application of the fully coupled modeling framework to gas-surface interactions relevant to hypersonic flight.
Bio: Iain D. Boyd is the Faculty Director of Government Relations and the James E. Knott Professor of Engineering at the University of Michigan. He received a Ph. D. in aeronautics and astronautics (1988) from the University of Southampton in England.
He worked for four years at NASA Ames Research Center in the areas of aerothermodynamics and space propulsion. Dr. Boyd was a faculty member in mechanical and aerospace engineering at Cornell University for six years. He joined the University of Michigan in 1999.
His research interests involve the development and application of physical models and computational methods for analysis of nonequilibrium gas and plasma dynamics processes. He has authored over 200 journal articles, more than 300 conference papers, and a book entitled “Nonequilibrium Gas Dynamics and Molecular Simulation.”
Dr. Boyd is a Fellow of the American Institute for Aeronautics & Astronautics (AIAA), and has received the 2018 AIAA Thermophysics Award and the 1998 AIAA Lawrence Sperry Award. He is also a Fellow of the American Physical Society and a Fellow of the Royal Aeronautical Society. Dr. Boyd serves on the editorial boards of the Journal of Thermophysics and Heat Transfer and Physical Review Fluids. Dr. Boyd was a member of the Air Force Scientific Advisory Board (AFSAB) and served as the Vice Chair of the Board (2013-2016).
