A heap is created when a powder is poured onto a surface. It is widely known that both the heap shape and the repose angle strongly rely on grain properties. Specifically, a non-cohesive powder ...

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 ...

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 ...
