Abstract
We simulate cohesive granular flows over an inclined plane using the 2D Contact Dynamics algorithm. The plug thickness is measured from numerical simulations considering various adhesive contact strengths. Flow surface roughness is investigated by calculating the fluctuation of surface topography. The distribution of fluctuation intensity across di↵erent adhesive strengths is also discussed. Roughness correlation on flow surface is studied using a pair correlation function applied to the positions of surface grains. A characteristic length is defined from the correlation results, considering both cohesive and non-cohesive cases. A quantitative comparison is conducted with a recent experimental study that relates the characteristic length to the agglomeration size in cohesive granular flows.
