A Volume of Fluid Immersed Boundary Method for Industrial Polymer Mixing
Emilia Capuano, Daniele Cerroni, Holger Marschall +3
This work develops advanced numerical methods for free-surface simulations of polymer mixing processes, integrating a Volume of Fluid (VOF) interface-capturing approach with a non-…
Learning cardiac activation and repolarization times with operator learning
Edoardo Centofanti, Giovanni Ziarelli, Nicola Parolini +3
Solving partial or ordinary differential equation models in cardiac electrophysiology is a computationally demanding task, particularly when high-resolution meshes are required to…
Non-isothermal non-Newtonian fluids: the stationary case
Maurizio Grasselli, Nicola Parolini, Andrea Poiatti +1
The stationary Navier-Stokes equations for a non-Newtonian incompressible fluid are coupled with the stationary heat equation and subject to Dirichlet type boundary conditions. The…
SEIHRDV: a multi-age multi-group epidemiological model and its validation on the COVID-19 epidemics in Italy
Luca Dede', Nicola Parolini, Alfio Quarteroni +2
We propose a novel epidemiological model, referred to as SEIHRDV, for the numerical simulation of the COVID-19 epidemic, which we validate using data from Italy starting in Septemb…
A model learning framework for inferring the dynamics of transmission rate depending on exogenous variables for epidemic forecasts
Giovanni Ziarelli, Stefano Pagani, Nicola Parolini +2
In this work, we aim to formalize a novel scientific machine learning framework to reconstruct the hidden dynamics of the transmission rate, whose inaccurate extrapolation can sign…
