Beyond classical similitude: group theoretic extrapolation of hypersonic stagnation-point boundary layers
Shujaut H. Bader, Daniel J. Bodony
Motivated by the need to extrapolate the results from ground-based experiments to the conditions of high-speed flight, we present the Lie equivalence symmetry analysis of the hyper…
GasNiTROM: Model Reduction via Non-Intrusive Optimization of Oblique Projection Operators and Guaranteed-Stable Latent-Space Dynamics
Cole J. Errico, Alberto Padovan, Daniel J. Bodony
Non-intrusive reduced-order modeling techniques are necessary for systems that are simulated using black-box solvers or known only from data. For systems exhibiting large transient…
From Coils to Surface Recession: Multiphysics Simulation of Ablation in ICP Wind Tunnels
Sanjeev Kumar, Alessandro Munafo, Blaine Vollmer +6
This work presents a multi-solver, coupled computational framework for predicting the thermo-chemical material response of thermal protection systems in inductively coupled plasma…
Resolvent4py: a parallel Python package for analysis, model reduction and control of large-scale linear systems
Alberto Padovan, Vishal Anantharaman, Clarence W. Rowley +3
In this paper, we present resolvent4py, a parallel Python package for the analysis, model reduction and control of large-scale linear systems with millions or billions of degrees o…
Surface instabilities in laminar compressible boundary layers with sublimation
Blaine Vollmer, Alberto Padovan, Daniel J. Bodony
Surface patterns on ablating materials are observed in high-speed ground and flight tests, but the mechanisms behind their formation are not known. In this paper, the origin of sur…
Petrov-Galerkin model reduction for collisional-radiative argon plasma
Ivan Zanardi, Alessandro Meini, Alberto Padovan +2
High-fidelity simulation of nonequilibrium plasmas -- crucial to applications in electric propulsion, hypersonic re-entry, and astrophysical flows -- requires state-specific collis…
