Summary
In this paper, the authors study the behavior of spherical glass beads when passed through a small hole and the diameter and tilt angle - dependence of the flow rate. They also study the condition for zero flux /clogging in terms of hole diameter and tilt angle.
The authors use granular medium consisting of spherical glass beads, with two different diameters: d = 0.30 ± 0.05 mm and d = 0.9 ± 0.1 mm. Both have bulk density of 1.53±0.01 g/cubic cm. and draining angle of repose of 24 degrees. As a medium to pass the bead through, two different containers are used - steel can and aluminum square tube. Holes are drilled in three different locations: in the bottom at center, in the bottom at 2 cm from the side, and in the side at 2 cm above the bottom.
