Experimental investigation and numerical modelling of density-driven segregation in an annular shear cell
Monica Tirapelle, Andrea Santomaso, Patrick Richard +1
Granular materials segregate spontaneously due to differences in particle size, shape, density and flow behaviour. In this paper we experimentally investigate density-difference-dr…
Mixing Grains with Different Elongation in a Rotating Drums
Claudia Piacenza, Marco Marconati, Colin Hare +2
Mixing grains with different properties is a remarkably challenging process, relevant to many industrial applications. Rotating drums have been used extensively as model systems to…
Radial segregation driven by axial convection
Andrea C. Santomaso, Luca Petenò, Paolo Canu
We experimentally study the mixing of binary granular systems in a horizontal rotating cylinder. When materials have the same size and differ by dynamic angle of repose only, we ob…
Scaling Laws for the Slip Velocity in Dense Granular Flows
Riccardo Artoni, Andrea C. Santomaso, Massimiliano Go' +1
In this Letter, the 2-dimensional dense flow of polygonal particles on an incline with a flat frictional inferior boundary is analyzed by means of contact dynamics discrete element…
Collapse of quasi-two-dimensional wet granular columns
Riccardo Artoni, Andrea C. Santomaso, Fabio Gabrieli +2
This paper deals with the experimental characterization of the collapse of wet granular columns in the pendular state, with the purpose of collecting data on triggering and jamming…
Effective boundary conditions for dense granular flows
Riccardo Artoni, Andrea Santomaso, Paolo Canu
We derive an effective boundary condition for granular flow taking into account the effect of the heterogeneity of the force network on sliding friction dynamics. This yields an in…
