A review on the angle of repose of granular materials

For powders which can be defined as small sized granular materials subject to cohesion and suspension in a gas the definition of the angle of repose is frequently linked with the Hausner ratio or the tapped to bulk density ratio [] and the powders will flow at angles greater than the angle of repose [] The angle of repose can also indicate the cohesiveness of the granular material
