Droplet velocity in both limits of low and high soluble surfactants in a Hele-Shaw cell: experimental and analytical results Open
The transport of droplets in microfluidic channels is strongly dominated by interfacial properties, which makes it a relevant tool for understanding the mechanisms associated with the presence of more or less soluble surfactants. In this p…

Discharge Flow of a Cohesive Granular Media from a Silo Open
Cohesion can dramatically affect the flow of granular media. In this Letter, thanks to a cohesion-controlled granular material, we propose to investigate experimentally the effect of the cohesion on the discharge from a silo. We use two ge…

Collapse of a cohesive granular column Open
The collapse of a quasi-two-dimensional column of cohesive granular media is investigated experimentally and numerically in the framework of a continuum model. The configuration is an initial parallelepiped-shaped granular pile, which is s…

Erosion of cohesive grains by an impinging turbulent jet Open
The erosion and transport of particles by an impinging turbulent jet in air is observed in various situations, such as the cleaning of a surface or during the landing of a spacecraft. The presence of inter-particle cohesive forces modifies…

Erosion of a cohesive granular material by an impinging turbulent jet Open
The erosion of a cohesive soil by an impinging turbulent jet is observed, for instance, during the landing of a spacecraft or involved in the so-called jet erosion test. To provide a quantitative understanding of this situation for cohesiv…

Flows of cohesive granular media Open
Cohesive granular media have broad applications in industries. However, our understanding of their flow behavior is still limited compared to dry granular media, although rich knowledge about their static and plastic properties has been ga…

The effect of cohesion on the discharge of a granular material through the orifice of a silo Open
We present the results of both experimental and numerical investigations of the silo discharge for a cohesive granular material. In our study, thanks to a cohesion-controlled granular material (CCGM) we propose to investigate the effect of…

Cohesion-controlled granular material Open
We present a simple method to prepare a granular material with a controlled cohesion between particles. The granular material is made of spherical glass beads coated with a polyborosiloxane polymer. This material is proved to be stable in …

Dip-coating of suspensions Open
Three regimes of dip coating in non-Brownian suspensions are identified: pure liquid, heterogeneous coating and homogeneous suspension films.
