Direct numerical simulations of inhalation in a 23-generation lung model
Marco Atzori, Emanuele Gallorini, Ciro Cottini +2
The air flows in the proximal and distal portions of the human lungs are interconnected: the lower Reynolds number in the deeper generations causes a progressive flow regularizatio…

A simple and efficient second-order immersed-boundary method for the incompressible Navier--Stokes equations
Paolo Luchini, Davide Gatti, Alessandro Chiarini +3
An immersed-boundary method for the incompressible Navier--Stokes equations is presented. It employs discrete forcing for a sharp discrimination of the solid-fluid interface, and a…

Understanding the mismatch between in-vivo and in-silico rhinomanometry
Marco Atzori, Gabriele Dini Ciacci, Maurizio Quadrio
Numerical simulations and clinical measurements of nasal resistance are in quantitative disagreement. Bias introduced by the design of medical devices has not been considered until…
