In our study of the origins of patterned formations on sublimating and ablating bodies, our local linear stability analysis has uncovered (what appears to be) the first known physical mechanism of their formation via differential ablation in laminar flows. More details on arXiv and a forthcoming article in the Journal of Fluid Mechanics. Congratulations to […]

Professor Bodony will give an invited lecture on Gas-Material Interactions for the NATO STO-AVT-358 LS on Advanced Computational Fluid Dynamic Methods for Hypersonic Flows, 1-4 December 2025.

Led by Dr. Alberto (Alby) Padovan, a Python-based package for analyzing large-scale linear systems, such as derived from fluid dynamics simulations, has been released on github: https://github.com/albertopadovan/resolvent4py. SoftwareX and arXiv have more documentation.

I am so pleased to announce that (now) Dr. Sandeep Murthy successfully defended his PhD thesis “Reducing Noise from Supersonic Jets using Linear Feedback Control informed by Resolvent Analysis” in January, 2025. Congratulations, Sandeep!

Bodony has been honored and will give the keynote talk at the 16th ERCOFTAC SIG 33 Workshop on Progress in Flow Instability, Transition, and Control, from June 30–July 2, 2025. More details to follow.

Congratulations to Dr. Fabian Dettenrieder for successfully defending his PhD thesis titled Fluid Structure Interaction in Compressible Viscous Flows in November, 2024.

Congratulations to Dr. Alby Padovan and Mr. Blaine Vollmer for their paper accepted to SIADS: Padovan, A., Vollmer, B., and Bodony, D. J. “Data-driven model reduction via non-intrusive optimization of projection operators and reduced-order dynamics,” accepted for publication in the SIAM Journal on Applied Dynamical Systems. Here’s the arXiv version.

In collaboration with the Center for Hypersonics and Entry System Studies, several post-doctoral opportunities are available. The full announcement is available here.

Building on our group’s success in modeling ablative systems and studying linear stability, we combined those capabilities to study the physical origins of differential ablation, found on many ablative systems but as-yet not fully explained. We are excited to work with our DoE partners at Sandia National Laboratory.

Professor Bodony delivered the keynote presentation at the APS March 2024 Meeting in the Focus Session on Extreme-Scale Computational Science Discovery in Fluid Dynamics and Related Disciplines.
