Dense flows of dry grains in a vertical chute controlled by the orifice consist in a steady and uniform plug flow with a thin shear layer near the rough walls. Using magnetic resonance imaging, we present detailed measurements of velocity profiles, and discuss the influence of the shear rate and of the wall roughness in the shear zone.
