Computational study of numerical flux schemes for mesoscale atmospheric flows in a Finite Volume framework
Nicola Clinco, Michele Girfoglio, Annalisa Quaini +1
We develop, and implement in a Finite Volume environment, a density-based approach for the Euler equations written in conservative form using density, momentum, and total energy as…
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…
Novel Methodologies for Solving the Inverse Unsteady Heat Transfer Problem of Estimating the Boundary Heat Flux in Continuous Casting Molds
Umberto Emil Morelli, Patricia Barral, Peregrina Quintela +2
In this work, we investigate the estimation of the transient mold-slab heat flux in continuous casting molds given some thermocouples measurements in the mold plates. Mathematicall…
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…
Non-linear manifold ROM with Convolutional Autoencoders and Reduced Over-Collocation method
Francesco Romor, Giovanni Stabile, Gianluigi Rozza
Non-affine parametric dependencies, nonlinearities and advection-dominated regimes of the model of interest can result in a slow Kolmogorov n-width decay, which precludes the reali…
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…
