Heat Transfer in Phase Change Materials with Multiple Fin Insertion
Paolo Proia, Mauro Sbragaglia, Giacomo Falcucci
We leverage 3D numerical simulations to study phase change materials (PCMs) cells under the effect of buoyancy forces. The solid PCM is heated from a source boundary, triggering me…
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 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…
