"Hypersonic Viscous Flows"
AME Lecture Hall, Room S212 | Zoom link
Hosted by Dr. Alex Craig
Abstract:
National interests in hypersonic flight provide motivation for accurate simulation of high-speed viscous flows, where combined viscous and high temperature gas effects are leading scientific challenges that limit system efficiencies and thermal management. The purpose of this presentation is to explain our approach in examining hypersonic transitional and turbulent flows. First, an overview key research challenges associated with hypersonic viscous flow is provided. Second, mathematical treatments founded in physics based second order turbulence transport, with algebraic reductions, are examined. Third, experimental and highfidelity simulation results are described that characterize the role of hypersonic effects on the hairpin structure, energy spectra, and Reynolds
averaged statistics, with comparison to Reynolds shear stress transport modeling. Fourth, a preview into current studies in experiments at high enthalpy is given. The presentation is concluded with a brief introduction to the OUSD JHTO University Consortium in Applied Hypersonics.
