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 -…

An adaptive, training-free reduced-order model for convection-dominated problems based on hybrid snapshots
Victor Zucatti, Matthew J. Zahr
The vast majority of reduced-order models (ROMs) first obtain a low dimensional representation of the problem from high-dimensional model (HDM) training data which is afterwards us…
