Filter Based Stabilization Methods for Reduced Order Models of Convection-Dominated Systems
In this thesis, I examine filtering based stabilization methods to design new regularized reduced order models (ROMs) for under-resolved simulations of unsteady, nonlinear, convection-dominated systems. The new ROMs proposed are variable delta filtering applied to the evolve-filter-relax ROM (V-EFR …

… and data assimilation. First, we consider a filter stabilization technique with a deconvolution-based indicator function for the simulation of advection-dominated advection-diffusion-reaction (ADR) problems with under-refined meshes. The proposed technique has been previously applied to the …
