The RBF Collocation Method to Design a Digital Twin for Coffee Percolation
Nadaniela Egidi, Lauro Fioretti, Josephin Giacomini +2
Espresso coffee extraction is a complex physico-chemical process and can be modeled through a system of coupled partial differential equations. We present a numerical solution base…

Inverse modeling of porous flow through deep neural networks: the case of coffee percolation
Antoniorenee Barletta, Salvatore Cuomo, Nadaniela Egidi +2
This work addresses the inverse problem of espresso coffee extraction, in which one aims to reconstruct the brewing conditions that generate a desired chemical profile in the final…
