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…
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-…
Instabilities of ring-rivulets: Impact of substrate wettability
Stefan Zitz, Andrea Scagliarini, Johan Roenby
Rivulets and droplets are naturally appearing shapes when small amounts of liquid are deposited on a partially wettable substrate. Here we study, by means of numerical simulations,…
