A linear filter regularization for POD-based reduced order models of the quasi-geostrophic equations

Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza

We propose a regularization for Reduced Order Models (ROMs) of the quasi-geostrophic equations (QGE) to increase accuracy when the Proper Orthogonal Decomposition (POD) modes retai…

An introduction to POD-Greedy-Galerkin reduced basis method

Pierfrancesco Siena, Michele Girfoglio, Gianluigi Rozza

Partial differential equations can be used to model many problems in several fields of application including, e.g., fluid mechanics, heat and mass transfer, and electromagnetism. A…

A novel Large Eddy Simulation model for the Quasi-Geostrophic Equations in a Finite Volume setting

Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza

We present a Large Eddy Simulation (LES) approach based on a nonlinear differential low-pass filter for the simulation of two-dimensional barotropic flows with under-refined meshes…

A Hybrid Reduced Order Model for nonlinear LES filtering

Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza

We develop a Reduced Order Model (ROM) for a Large Eddy Simulation (LES) approach that combines a three-step algorithm called Evolve-Filter-Relax (EFR) with a computationally effic…
