Description

Fluid-Structure Interactions in Hypersonic Flight
Daniel Bodony, Ph.D.

ABSTRACT: The interaction of high-speed aerodynamics with thermo-mechanically compliant structures is a critical design consideration for single-use and reusable hypersonic vehicles. Historical techniques for predicting fluid-thermal-structure interaction (FTSI) have been shown to be insufficient for envisioned flight vehicles, leading to a resurgent effort towards understanding, modeling, and predicting FTSI-coupled systems. In this talk, we will discuss the impact of FTSI on two fundamental scenarios -- high-speed boundary layer transition and shock-boundary layer interaction -- informed using a combination of local and global stability and direct numerical simulation techniques. In each scenario, focus will be given to the physical aspects of the FTSI-enabled coupling. Supporting details on the relevant theoretical and numerical details required for accurate prediction will also be discussed.

BIO: Daniel J. Bodony is the Blue Waters Associate Professor and Donald Biggar Willett Faculty Scholar in the Department of Aerospace Engineering at the University of Illinois. He received his Ph.D. in Aeronautics & Astronautics from Stanford University in 2005. After working at the NASA Ames/Stanford Center for Turbulence Research he joined the University of Illinois in late 2006 as an assistant professor. He received an NSF CAREER award in 2012 in Fluid Dynamics, is an associate Fellow of the AIAA, and recently received the University of Illinois' William L. Everitt Award for Teaching Excellence. In 2019 he became the Associate Head for Graduate Programs.
