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…
Lagrangian statistics of dense emulsions
Ivan Girotto, Andrea Scagliarini, Roberto Benzi +1
The dynamics of dense stabilized emulsions presents a rich phenomenology including chaotic emulsification, non-Newtonian rheology and ageing dynamics at rest. Macroscopic rheology…
Three-dimensional active turbulence in microswimmer suspensions: simulations and modelling
Antonio Gascó, Ignacio Pagonabarraga, Andrea Scagliarini
Active turbulence is a paradigmatic and fascinating example of self-organized motion at large scales occurring in active matter. We employ massive hydrodynamic simulations of suspe…
A lattice Boltzmann model for self-diffusiophoretic particles near and at liquid-liquid interfaces
Lucas Palacios, Andrea Scagliarini, Ignacio Pagonabarraga
We introduce a novel mesoscopic computational model based on a multiphase-multicomponent lattice Boltzmann method for the simulation of self-phoretic particles in the presence of l…
Build up of yield stress fluids via chaotic emulsification
Ivan Girotto, Roberto Benzi, Gianluca Di Staso +3
Stabilized dense emulsions display a rich phenomenology connecting microstructure and rheology. In this work we study how an emulsion with a finite yield stress can be built via la…
Hydrodynamic and geometric effects in the sedimentation of model run-and-tumble bacteria
Andrea Scagliarini, Ignacio Pagonabarraga
The sedimentation process in a suspension of bacteria is the result of the competition between gravity and the intrinsic motion of the microorganisms. We perform simulations of run…
Discrete fluidization of dense monodisperse emulsions in neutral wetting microchannels
Linlin Fei, Andrea Scagliarini, Kai H. Luo +1
The rheology of pressure-driven flows of two-dimensional dense monodisperse emulsions in neutral wetting microchannels is investigated by means of mesoscopic lattice simulations, c…
On the impact of controlled wall roughness shape on the flow of a soft-material
F. Pelusi, M. Sbragaglia, A. Scagliarini +3
We explore the impact of geometrical corrugations on the near-wall flow properties of a soft-material driven in a confined rough microchannel. By means of numerical simulations, we…
Unravelling the role of phoretic and hydrodynamic interactions in active colloidal suspensions
Andrea Scagliarini, Ignacio Pagonabarraga
Active fluids comprise a variety of systems composed of elements immersed in a fluid environment which can convert some form of energy into directed motion; as such they are intrin…
Fluidisation and plastic activity in a model soft-glassy material flowing in micro-channels with rough walls
Andrea Scagliarini, Matteo Lulli, Massimo Bernaschi +1
By means of mesoscopic numerical simulations of a model soft-glassy material, we investigate the role of boundary roughness on the flow behaviour of the material, probing the bulk/…
Mesoscopic simulation study of wall roughness effects in micro-channel flows of dense emulsions
Andrea Scagliarini, Mauro Sbragaglia, Massimo Bernaschi
We study the Poiseuille flow of a soft-glassy material above the jamming point, where the material flows like a complex fluid with Herschel- Bulkley rheology. Microscopic plastic r…
Non-locality and viscous drag effects on the shear localisation in soft-glassy materials
Andrea Scagliarini, Benjamin Dollet, Mauro Sbragaglia
We study the Couette flow of a quasi-2d soft-glassy material in a Hele-Shaw geometry. The material is chosen to be above the jamming point, where a yield stress emerges, belo…
Internal dynamics and activated processes in Soft-Glassy materials
R. Benzi, M. Sbragaglia, A. Scagliarini +4
Plastic rearrangements play a crucial role in the characterization of soft-glassy materials, such as emulsions and foams. Based on numerical simulations of soft-glassy systems, we…
