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 ...

The pile would become slightly shorter as it became broader at its base. The concept is known as the angle of repose, that place where movement ceases and the material is at rest, so to speak.

also called “dynamic angle of repose” in the literature, is calculated from the average interface position. A low value of the flowing angle corresponds to excellent flowability. A broad set of ...
