Monodisperse dry granular flows on inclined planes: role of roughness.
Recent studies have pointed out the importance of the basal friction on the dynamics of granular flows. We present experimental results on the influence of the roughness of the inclined plane on the dynamics of a monodisperse dry granular flow. We found experimentally that there exists a maximum of the friction for a given relative roughness. This maximum is shown to be independent of the slope...
متن کاملParticle Image Velocimetry (PIV) for Granular Avalanches on Inclined Planes
This paper is concerned with experimental results of sand avalanches flowing down inclined plexiglass chutes with lateral confinement. Specifically we introduce the particle image velocimetry (PIV) technique for granular avalanches. We discuss the differences and problems in comparison with “usual” PIV. After this, we present surface and side velocity measurements that are obtained at different...
متن کاملCollapse of granular-liquid mixtures over rigid, inclined beds.
This work deals with the propagation of granular-liquid waves over rigid beds, originated by the sudden removal of a sluice gate in a rectangular, inclined flume. In particular, we experimentally investigate the role of the initial volume ratio of granular material-monodispersed plastic cylinders-to water, the flume width, and the bed roughness on the time evolution of the granular front. Due t...
متن کاملRapid granular ow on a rough inclined
Flow on an inclined plane is both one of the most common situations encountered in granular ows, as well as one of the most extensively studied geometries in their theoretical treatment. Nevertheless, so far there are very few systematic studies concerning the innuence of the (dissipative) material properties on the ow. Here, numerical simulations are presented where the focus is on the innuenc...
متن کاملTsunami generated by a granular collapse down a rough inclined plane
In this Letter, we experimentally investigate the collapse of initially dry granular media into water and the subsequent impulse waves. We systematically characterize the influence of the slope angle and the granular material on the initial amplitude of the generated leading wave and the evolution of its amplitude during the propagation. The experiments show that whereas the evolution of the le...
