A molecular dynamics simulation technique is applied to the modelling of a granular chute flow, and the density and velocity profiles of the chute flows are examined by considering different inclination angles, rough and smooth boundary conditions, accelerating and fully developed Bows. In general, the chute velocity profiles are non-linear, concave in shape and there is a slip velocity at the chute base. However, a linear velocity profile with no boundary slip can be obtained at small inclination angles and therefore a slow Bow regime. For fully developed flows, the density profiles show no low density zone near the chute base, but a density profile with a low density zone near the base surface can be obtained at an accelerating stage for a rough base. A rough boundary can produce both resistance and anti-rotational effects on the flow.
