The Department of Mechanical, Materials, and Aerospace Engineering presents its spring 2025 seminar series featuring Dan Bodony, Blue Waters Professor of Aerospace Engineering, a Donald Biggar Willett Faculty Scholar, and associate dean for Graduate, Professional, and Online Programs in the Grainger College of Engineering at the University of Illinois at Urbana-Champaign, who will present “Fluid-Structure Interactions Relevant to Hypersonic Flows.” This seminar is open to the public and will take place on Wednesday, February 12, from 12:45–1:45 p.m. in room 104 of the Rettaliata Engineering Center.

Abstract

The fluid dynamics of high-speed flows (characterized by Mach numbers greater than five or enthalpies of tens of MJ/kg) past aerodynamically-shaped objects is characterized by instabilities, turbulence, and shocks, possibly in chemical and/or thermal non-equilibrium, and their interactions with adjacent structures and materials. We seek to understand the details of these interactions through the use of flow stability analysis and direct numerical simulations of the compressible turbulent reactive (possibly non-equilibrium) flow coupled with material response simulations of the adjacent structure. Our computational approach utilizes multiple domain-specific codes built for heterogeneous computing architectures that are coupled through a data exchange and time integration framework while our analytical approach also fully couples the fluid and solid mechanics. The presentation will describe these tools and their results through application on key problems of interest, such as Mach 6 shock-laden flows interacting compliant panels studied in NASA Langley's 20-inch tunnel, and the non-equilibrium flow within UIUC's Plasmatron-X inductively coupled plasma torch and the response of an ablative material placed within it.

Biography

Daniel J. Bodony is the Blue Waters Professor of Aerospace Engineering, a Donald Biggar Willett Faculty Scholar, and associate dean for Graduate, Professional, and Online Programs in the Grainger College of Engineering at the University of Illinois at Urbana-Champaign. Recent acknowledgments include the Campus Promotion with Distinction Award (2020) and the Rose Award for Teaching Excellence (2022). Upon receiving his Ph.D. in aeronautics and astronautics from Stanford University in 2005, he was a research scientist at the NASA Ames/Stanford University Center for Turbulence Research before joining UIUC in 2006. He received a National Science Foundation CAREER award in 2012 in fluid dynamics and is an associate fellow of the American Institute for Aeronautics and Astronautics. His research focuses on the simulation and modeling of high-speed compressible flows, with specialties in fluid-thermal-structural interaction, control of shock-laden flows, and aeroacoustics.
