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 POD-Galerkin reduced order model for the Navier-Stokes equations in stream function-vorticity formulation
Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza
We develop a Proper Orthogonal Decomposition (POD)-Galerkin based Reduced Order Model (ROM) for the efficient numerical simulation of the parametric Navier-Stokes equations in the…
An efficient FV-based Virtual Boundary Method for the simulation of fluid-solid interaction
Michele Girfoglio, Giovanni Stabile, Andrea Mola +1
In this work, the Immersed Boundary Method (IBM) with feedback forcing introduced by Goldstein et al. (1993) and often referred in the literature as the Virtual Boundary Method (VB…
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…
