Shear of granular material in a confined shear box

Confined chute flows on erodible base: gap between sidewalls : 30 grains size, angle 24 deg. (left) and 30 deg. (right)

Granular flow driven by gravity and confined between sidewalls (30 000 grains). The flow angle is 45° and the gap between sidewalls is 10 grain sizes. The vertical profile of the velocity (in the main flow direction) is also reported.

Unconfined granular flows on a byumpy bottom, the angle of inclination is 25°, the friction coefficient between grains is 0.5
