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…
A non column based fully unstructured implementation of Kessler s microphysics with warm rain using continuous and discontinuous spectral elements
Yassine Tissaoui, Simone Marras, Annalisa Quaini +2
Numerical weather prediction is pushing the envelope of grid resolution at local and global scales alike. Aiming to model topography with higher precision, a handful of articles in…
A data-driven Reduced Order Method for parametric optimal blood flow control: application to coronary bypass graft
Caterina Balzotti, Pierfrancesco Siena, Michele Girfoglio +2
We consider an optimal flow control problem in a patient-specific coronary artery bypass graft with the aim of matching the blood flow velocity with given measurements as the Reyno…
Data-Driven Enhanced Model Reduction for Bifurcating Models in Computational Fluid Dynamics
Martin W. Hess, Annalisa Quaini, Gianluigi Rozza
We investigate various data-driven methods to enhance projection-based model reduction techniques with the aim of capturing bifurcating solutions. To show the effectiveness of the…
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…
