Granular surface flows confined between flat, frictional walls. Part 1. Kinematics
Patrick Richard, Alexandre Valance, Renaud Delannay +1
We report and analyse the results of extensive discrete element method simulations of three-dimensional gravity driven flows of cohesionless granular media over an erodible bed, th…
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…
Compressibility regularizes the "" rheology for granular flows
J. Heyman, R. Delannay, H. Tabuteau +1
The -rheology has been recently proposed as a potential candidate to model the flow of frictional grains in a dense inertial regime. However, this rheology was shown to be il…
