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 forms ...

The GranuDrum instrument is an automated powder flowability measurement technique predicated on the rotating drum principle. The drum is a horizontal cylindrical with transparent sidewalls and it is ...

The prediction of the angle of repose for raised mounds of dry cohesive granular material is a long-standing problem in the natural sciences and in industry. Using numerical (particle-based) ...

Flowability index: Flowability index is useful to evaluate the flow characterization of the powder sample. Based on the Carr Flowability chart, it is weighted sum of the angle of repose, ...
