چکیده

We use a momentum balance to interpret numerical simulations of dense, steady, fully-developed inclined granular flows of spheres on an erodible base confined between flat frictional side walls. We observe an exponential profile of mean volume fraction in the direction perpendicular to the base and suggest a scaling for its characteristic length. We also predict volume fraction and mean velocity profiles in the ballistic region above the free surface.

Role of Couple Stresses in Shallow Granular Flows down a Bumpy Incline

We extend the micropolar fluid theory of Hayakawa and Mitarai, et al. [PRL 88, 174301 (2002)] to dense, relatively shallow flows of spherical grains down an inclined plane on which spherical bumps have been affixed. We update the model of Louge [PRE 67, 061303 (2003)], and show the role played by couple stresses in establishing the solid volume fraction in the core of the flow.

Transverse instability of avalanches in granular flows down an incline.

Avalanche experiments on an erodible substrate are analyzed using the "partial fluidization" model of dense granular flows. The model identifies a family of propagating solitonlike avalanches with shape and velocity controlled by the inclination angle and the depth of the substrate. At high inclination angles, the solitons display a transverse instability, followed by coarsening and fingering s...

Diphasic non - local model for granular surface flows

– Considering recent results revealing the existence of multi-scale rigid clusters of grains embedded in granular surface flows, i.e. flows down an erodible bed, we describe here the surface flows rheology through a non-local constitutive law. The predictions of the resulting model are compared quantitatively to experimental results: The model succeeds to account for the counter-intuitive shape...

Fundamental changes of granular flow dynamics, deposition, and erosion processes at high slope angles: Insights from laboratory experiments

Entrainment of underlying debris by geophysical flows can significantly increase the flow deposit extent. To study this phenomenon, analog laboratory experiments have been conducted on granular column collapse over an inclined channel with and without an erodible bed made of similar granular material. Results show that for slope angles below a critical value θc, between 10◦ and 16◦, the run out...

Erosion and mobility in granular collapse over sloping beds

[1] We describe laboratory experiments of granular material flowing over an inclined plane covered by an erodible bed, designed to mimic erosion processes of natural flows travelling over deposits built up by earlier events. Two controlling parameters are the inclination of the plane and the thickness of the erodible layer. We show that erosion processes can increase the flowmobility (i.e., run...
