On the hydrodynamic behaviour of the immersed boundary -- lattice Boltzmann method for wetting problems
Elisa Bellantoni, Fabio Guglietta, Andreas Demou +6
We study the hydrodynamic behaviour of a mesoscale numerical model for wetting dynamics based on the immersed boundary - lattice Boltzmann (IBLB) method. This IBLB model features a…
A numerical study on plasma acceleration processes with ion dynamics at the sub-nanosecond timescale
G. Parise, A. Cianchi, M. Galletti +5
Plasma wakefield acceleration is a groundbreaking technique for accelerating particles, capable of sustaining gigavolt-per-meter accelerating fields. Understanding the physical mec…
A reduced model for droplet dynamics with interfacial viscosity
Fabio Guglietta, Diego Taglienti, Mauro Sbragaglia
We propose an extension of the phenomenological Maffettone-Minale (MM) model (P.L. Maffettone and M. Minale, J. Non-Newton. Fluid Mech. 78, 227-241 (1998)) to describe the time-dep…
A note on thermal effects in non-linear models for plasma-based acceleration
D. Simeoni, G. Parise, A. R. Rossi +3
We investigate the impact of a non-negligible background temperature on relativistic plasma wake-fields generated when a beam of charged particles passes through a neutral plasma a…
Thermal wakefield structure in plasma acceleration processes: insights from fluid models and PIC simulations
Daniele Simeoni, Andrea Renato Rossi, Gianmarco Parise +2
We focus on the process of plasma acceleration in the presence of non-negligible thermal effects, wherein a driver of relativistic electrons perturbs a warm neutral plasma and gene…
Hemodynamic effects of intra- and supra- deployment locations for a bioprosthetic aortic valve
Martino Andrea Scarpolini, Giovanni Vagnoli, Fabio Guglietta +2
Aortic valve replacement is a key surgical procedure for treating aortic valve pathologies, such as stenosis and regurgitation. The precise placement of the prosthetic valve relati…
