Experimental assessment of the effective friction at the base of granular chute flows on smooth incline
Olivier Roche, Siet van den Wildenberg, Alexandre Valance +4
We report on direct measurements of the basal force components for granular material flowing down a smooth incline. We investigate granular flows for a large range of inclination a…
Influence of lateral confinement on granular flows: comparison between shear-driven and gravity-driven flows
Patrick Richard, Riccardo Artoni, Alexandre Valance +1
The properties of confined granular flows are studied through discrete numerical simulations. Two types of flows with different boundaries are compared: (i) gravity-driven flows to…
High-speed confined granular flows down inclines revisited
Y. Zhu, R. Delannay, A. Valance
Recent numerical work has shown that high-speed confined granular flows down inclines exhibit a rich variety of flow patterns, including dense unidirectional flows, flows with long…
Grain-scale Modeling and Splash Parametrization for Aeolian Sand Transport
Marc Lämmel, Kamil Dzikowski, Luc Oger +2
The collision of a spherical grain with a granular bed is commonly parametrized by the splash function, which provides the velocity of the rebounding grain and the velocity distrib…
New patterns in high-speed granular flows
Nicolas Brodu, Renaud Delannay, Alexandre Valance +1
We report on new patterns in high-speed flows of granular materials obtained by means of extensive numerical simulations. These patterns emerge from the destabilization of unidirec…
