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…
Rayleigh-Bénard thermal convection in emulsions: a short review
Francesca Pelusi, Andrea Scagliarini, Mauro Sbragaglia +2
Thermally driven emulsions arise in a broad range of natural and industrial contexts, yet their fundamental physical understanding remains only partially established. Emulsions exh…

Elisa Bellantoni, Fabio Guglietta, Francesca Pelusi +5
We develop a mesoscale computational model to describe the interaction of a droplet with a solid. The model is based on the hybrid combination of the immersed boundary and the latt…
When to Boost: How Dose Timing Determines the Epidemic Threshold
Alessandro Celestini, Francesca Colaiori, Stefano Guarino +3
Most vaccines require multiple doses, the first to induce recognition and antibody production and subsequent doses to boost the primary response and achieve optimal protection. We…
A note on the lattice momentum balance in the lattice Boltzmann interaction-framework
Francesca Pelusi, Matteo Lulli, Christophe Coreixas +2
In this note, we show how the exploitation of the lattice momentum balance condition allows to envisage an analytical procedure to define the lattice pressure tensor (LPT) for the…

Francesca Pelusi, Andrea Scagliarini, Mauro Sbragaglia +2
Emulsions are paramount in various interdisciplinary topical areas, yet a satisfactory understanding of their behavior in buoyancy-driven thermal flows has not been established. In…
Intermittent thermal convection in jammed emulsions
Francesca Pelusi, Andrea Scagliarini, Mauro Sbragaglia +2
We study the process of thermal convection in jammed emulsions with a yield-stress rheology. We find that heat transfer occurs via an intermittent mechanism, whereby intense short-…
Analytical prediction for the steady-state behavior of a confined drop with interface viscosity under shear flow
Fabio Guglietta, Francesca Pelusi
The steady-state behavior of a single drop under shear flow has been extensively investigated in the limit of small deformation and negligible inertia effects. In this work, we com…
