Non-Intrusive Balancing for Data-Driven Model Reduction with Oblique Projections
Alberto Padovan
Non-intrusive reduced-order modeling is essential for systems simulated with black- or gray-box solvers, yet computing accurate data-driven models remains challenging when the dyna…
Geometry-controlled heat transport in differentially heated cavity through the lens of DNS and resolvent analysis
Krishan Chand, Michael Quan, Alberto Padovan +1
We perform direct numerical simulations (DNS) and resolvent analysis of natural convection in a differentially heated cavity (DHC) at Prandtl number , systematically vary…
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…
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…
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 thermochemical nonequilibrium gas mixtures
Ivan Zanardi, Alberto Padovan, Daniel J. Bodony +1
State-specific thermochemical collisional models are crucial to accurately describe the physics of systems involving nonequilibrium plasmas, but they are also computationally expen…
Data-driven model reduction via non-intrusive optimization of projection operators and reduced-order dynamics
Alberto Padovan, Blaine Vollmer, Daniel J. Bodony
Computing reduced-order models using non-intrusive methods is particularly attractive for systems that are simulated using black-box solvers. However, obtaining accurate data-drive…
Multi-domain analysis and prediction of the light emitted by an inductively coupled plasma jet
Lorenzo Capponi, Alberto Padovan, Gregory S. Elliott +3
Inductively coupled plasma wind tunnels are crucial for replicating hypersonic flight conditions in ground testing. Achieving the desired conditions (e.g., stagnation-point heat fl…
An Extended B' Formulation for Ablating-Surface Boundary Conditions
Alberto Padovan, Blaine Vollmer, Francesco Panerai +3
The B' formulation can be understood as a mass and energy conservation formalism at a reacting singular surface. In hypersonics applications, it is typically used to compute the ch…
