Coupling Heterarchical Granular Dynamics and Computational Fluid Dynamics
Jiahuan Li, Shivakumar Athani, Alistair Gillespie +3
Granular flows in ambient fluids exhibit grain-size-dependent segregation, which is difficult to capture efficiently with existing models, especially in large-scale systems involvi…
Scale dependence of segregation patterns in the filling of silos
Shivakumar Athani, Benjy Marks, François Guillard +2
Size segregation in granular flows is a well-known phenomenon: laboratory experiments consistently show that large particles migrate toward silo walls during filling, while smaller…
Heterarchical Granular Dynamics
Benjy Marks, Shivakumar Athani, Itai Einav
The two most commonly used methods to model the behaviour of granular flows are discrete element and continuum mechanics simulations. These approaches concentrate on the determinis…
Partially Saturated Granular Flow in a Rotating Drum: The Role of Cohesion
Mingrui Dong, Zhongzheng Wang, Benjy Marks +2
Partially saturated granular flows are common in various natural and industrial processes, such as landslides, mineral handling, and food processing. We conduct experiments and app…
The effect of grain size on erosion and entrainment in dry granular flows
Eranga Dulanjalee, François Guillard, James Baker +1
The entrainment of underlying erodible material by geophysical flows can significantly boost the flowing mass and increase the final deposition extent. The particle size of both th…
Compaction of granular material inside confined geometries
Benjy Marks, Bjørnar Sandnes, Guillaume Dumazer +2
In both nature and engineering, loosely packed granular materials are often compacted inside confined geometries. Here, we explore such behaviour in a quasi-two dimensional geometr…
