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…
Role of interfacial stabilization in the Rayleigh-Bénard convection of liquid-liquid dispersions
Francesca Pelusi, Andrea Scagliarini, Mauro Sbragaglia +2
Based on mesoscale lattice Boltzmann numerical simulations, we characterize the Rayleigh-Bénard (RB) convective dynamics of dispersions of liquid droplets in another liquid phase.…
Dynamical regimes of thermally convective emulsions
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…
Immersed boundary - lattice Boltzmann method for wetting problems
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…
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-…
