Model reduction of convection-dominated viscous conservation laws using implicit feature tracking and landmark image registration
Victor Zucatti, Matthew J. Zahr
Reduced-order models (ROMs) remain generally unreliable for convection-dominated problems, such as those encountered in hypersonic flows, due to the slowly decaying Kolmogorov -…

Data-Driven Closure of Projection-Based Reduced Order Models for Unsteady Compressible Flows
Victor Zucatti, William Wolf
A data-driven closure modeling based on proper orthogonal decomposition (POD) temporal modes is used to obtain stable and accurate reduced order models (ROMs) of unsteady compressi…

Calibration of projection-based reduced-order models for unsteady compressible flows
Victor Zucatti, William R. Wolf, Michel Bergmann
An analysis of calibration for reduced-order models (ROMs) is presented in this work. The Galerkin and least-squares Petrov-Galerkin (LSPG) methods are tested on compressible flows…
