Fig. 2: Comparisons between the experimental and simulated particle packing and static angle of repose for various particle shapes.

The shapes included for comparisons are (a) sphere, (b) short-axis sphero-polygon, (c) short-axis hexagonal-prism, (d) elongated sphero-cylinder, (e) elongated sphero-polygon, and (f) elongated hexagonal-prism. Shown from left to right are the following: 3D-printed PA12 particles, μCT-scanned images of the particle packing in the cube container from a side view and a 3D view, repose of particles on the rough tray, DEM configurations of the simulated particle, simulated particle packing of the particle packing in the cube container from a side view and a 3D view, and simulated repose of particles.
