The higher kinetic friction obtained on snow is attributed ... exhibits a considerable angle of repose.

It is widely known that both the heap shape and the repose angle strongly rely on grain properties. Specifically, a non-cohesive powder forms a regular conical heap, while a cohesive powder forms an ...

Consequently, for each rotating speed, the dynamic cohesive index is measured from the interface fluctuations, and the flowing angle, also called “dynamic angle of repose” in the ... and the friction ...
