Reduced Order Models for the Quasi-Geostrophic Equations: A Brief Survey

Changhong Mou, Zhu Wang, David R. Wells +2

Reduced order models (ROMs) are computational models whose dimension is significantly lower than those obtained through classical numerical discretizations (e.g., finite element, f…

Closure Learning for Nonlinear Model Reduction Using Deep Residual Neural Network

Xuping Xie, Clayton G. Webster, Traian Iliescu

Developing accurate, efficient, and robust closure models is essential in the construction of reduced order models (ROMs) for realistic nonlinear systems, which generally require d…

Lagrangian Data-Driven Reduced Order Modeling of Finite Time Lyapunov Exponents

Xuping Xie, Peter J. Nolan, Shane D. Ross +2

There are two main strategies for improving the projection-based reduced order model (ROM) accuracy: (i) improving the ROM, i.e., adding new terms to the standard ROM; and (ii) imp…

Calibrated Filtered Reduced Order Modeling

X. Xie, M. Mohebujjaman, L. G. Rebholz +1

We propose a calibrated filtered reduced order model (CF-ROM) framework for the numerical simulation of general nonlinear PDEs that are amenable to reduced order modeling. The nove…

Numerical Analysis of the Leray Reduced Order Model

Xuping Xie, David Wells, Zhu Wang +1

Standard ROMs generally yield spurious numerical oscillations in the simulation of convection-dominated flows. Regularized ROMs use explicit ROM spatial filtering to decrease these…

An Evolve-Then-Filter Regularized Reduced Order Model

David Wells, Zhu Wang, Xuping Xie +1

In this paper, we propose a new evolve-then-filter reduced order model (EF-ROM). This is a regularized ROM (Reg-ROM), which aims at the numerical stabilization of proper orthogonal…
