From: The effect of particle shape on discharge and clogging
Dry granular flow: number of particles discharged before clogging as a function of the size ratio do/d. Granular shapes: (a) spheres, (b) 2D cross, (c) 3D cross and (d) cubes. Datapoints: 134 independent experimental realizations. Lines: power function (Eq. 3). The γ-exponents selected to capture the lower (γ = 2) and upper (γ = 3) bounds. *The upper bound for the 2D cross data takes into consideration particle flatness (Eq. 4).
