Furthermore, we also compared the simulated angle of repose of mono-sized iron ore granules with the experimental result when the granule size increased from 5.0 to 9.0 mm. Fig. 12 shows the experimental trend and the simulated ones obtained using the friction coefficient combinations C1–C6. It can be seen that the simulated angles of repose for C2, C4 and C5 are still a better match to the ...

Angle of repose - Wikipedia

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0 to 90 . The morphology of the material affects the angle of repose; smooth, rounded ...
