Numerical Investigations of Particle Interactions with Navy Relevant High-Speed Flows
Abstract
Hypersonic flight technology provides increased range and reduced travel time of defense hardware, thereby enabling a strategic large-range rapid response capability. Therefore, hypersonics research is currently one of the highest technical priorities for the Department of Defense and the Navy. The ability to accurately predict the complex flow field around hypersonic flight hardware and provide a profound understanding of the relevant physics is essential to reduce design margins and system uncertainties, and, ultimately, guide the development of novel innovative designs. Current and future hypersonic vehicles are designed to obtain optimal aero-thermodynamic characteristics while operating in the atmosphere for sustained period of times. The external disturbance environment, including free-stream turbulence, thermal noise associated with kinetic fluctuations and particulates can strongly affect the aero-thermodynamics of high-speed vehicles, in particular, the laminar-turbulent transition process, which is the main subject of this research.
