Inertial Force Transmission in Dense Granular Flows
Matthew Macaulay, Pierre Rognon
Dense granular flows are well described by several continuum models, however, their internal dynamics remain elusive. This study explores the contact force distributions in simulat…
Viscosity of Cohesive Granular Flows
Matthew Macaulay, Pierre Rognon
Cohesive granular materials such as wet sand, snow, and powders can flow like a viscous liquid. However, the elementary mechanisms of momentum transport in such athermal particulat…
Mobility in immersed granular materials upon cyclic loading
Tanvir Hossain, Pierre Rognon
We study the mobility of objects embedded in an immersed granular packing and subjected to cyclic loadings. In this aim, we conducted experiments using glass beads immersed in wate…
Drag force in immersed granular materials
Tanvir Hossain, Pierre Rognon
We investigate the drag forces acting on large objects moving through a granular packing immersed in water. In this aim, we conducted uplift experiments involving pulling out horiz…
Inertial drag in granular media
Shivakumar Athani, Pierre Rognon
Like in liquids, objects moving in granular materials experience a drag force. We investigate here whether and how the object acceleration affect this drag force. The study is base…
Shear-induced diffusion in non-local granular flows
Prashidha Kharel, Pierre Rognon
We investigate the properties of self-diffusion in heterogeneous dense granular flows involving a gradient of stress and inertial number. The study is based on simulated plane shea…
