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…
Non-reciprocal coalescence-breakup dynamics in concentrated emulsions
Ivan Girotto, Andrea Scagliarini, Lei Yi +3
Dense stabilized emulsions are mixtures of immiscible fluids where the high-volume fraction droplet dispersed phase is stabilized against coalescence by steric interactions. The pr…
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-…
The emergence of supramolecular forces from lattice kinetic models of non ideal fluids: applications to the rheology of soft glassy meterials
M. Sbragaglia, R. Benzi, M. Bernaschi S. Succi
A systematic study for a single-specie lattice Boltzmann model with frustrated-short range attractive and mid/long-range repulsive-interactions is presented. The equilibrium analys…
Rheological properties of soft-glassy flows from hydro-kinetic simulations
R. Benzi, M. Bernaschi, M. Sbragaglia +1
Based on numerical simulations of a lattice kinetic model for soft-glassy materials, we characterize the global rheology of a dense emulsion-like system, under three representative…
Phase-field model of long-time glass-like relaxation in binary fluid mixtures
R. Benzi, M. Sbragaglia, M. Bernaschi +1
We present a new phase-field model for binary fluids exhibiting typical signatures of self-glassiness, such as long-time relaxation, ageing and long-term dynamical arrest. The pres…
Herschel-Bulkley rheology from lattice kinetic theory of soft-glassy materials
R. Benzi, M. Bernaschi, M. Sbragaglia +1
We provide a clear evidence that a two species mesoscopic Lattice Boltzmann (LB) model with competing short-range attractive and mid-range repulsive interactions supports emergent…
Mesoscopic lattice Boltzmann modeling of soft-glassy systems: theory and simulations
R. Benzi, M. Sbragaglia, S. Succi +2
A multi-component lattice Boltzmann model recently introduced (R. Benzi et al. Phys. Rev. Lett 102, 026002 (2009)) to describe some dynamical behaviors of soft-flowing materials is…
Lattice Boltzmann method with self-consistent thermo-hydrodynamic equilibria
M. Sbragaglia, R. Benzi, L. Biferale +3
Lattice kinetic equations incorporating the effects of external/internal force fields via a shift of the local fields in the local equilibria, are placed within the framework of co…
Extended Self Similarity in numerical simulations of 3D anisotropic turbulence
R. Benzi, M. V. Struglia, R. Tripiccione
Using a code based on the Lattice Boltzmann Equation, we have performed numerical simulations of a turbulent shear flow. We investigate the scaling behaviour of the structure funct…
A new scaling property of turbulent flows
R. Benzi, L. Biferale, S. Ciliberto +2
We discuss a possible theoretical interpretation of the self scaling property of turbulent flows (Extended Self Similarity). Our interpretation predicts that, even in cases when ES…
