WebJan 15, 2024 · Flow and clog in a silo with an oscillating exit. Phys. Rev. E (2024) A. Ashour et al. Silo outflow of soft frictionless spheres. Phys. Rev. Fluids ... The effects of the stirring shaft angular velocity, the dimensionless depth of granular materials, and the discharge exit angle on the discharge in the silo were compared. An enhancement factor ... WebFor dry granular materials falling through a circular exit at the bottom of a silo, no continuous flow can be sustained when the diameter D of the exit is less than five times the characteristic size of the grains. If the bottom of the silo rotates horizontally with respect to the wall of the silo, finite flow rate can be sustained even at small D.

WebJun 18, 2024 · Correspondingly, the average flow rate of the particles through the exit abruptly rises, at least one order of magnitude better than that with an immobile obstacle and approaching to the flow rate of a continuous flow. The rotation enhances the breakage of clogging arches, which is responsible for improving the flowability in the horizontal silo.
WebAug 30, 2024 · We demonstrate experimentally that clogging in a silo correlates with some features of the particle velocities in the outlet proximities. This finding, that links the formation of clogs with a kinematic property of the system, is obtained by looking at the effect that the position of the lateral walls of the silo has on the flow and clogging behavior. grant county ky weekly weatherWebJun 18, 2024 · The external perturbation applied on a silo and the placement of an immobile obstacle before an exit are two common and effective ways to diminish the clogging in … chip aikensWebFlow and Clog in a Silo with Oscillating Exit: Speaker: Prof. Kiwing To, Institute of Physics, Academia Sinica: Date: 9 January 2024 (Tuesday) Time: 11:00 to 12:30: Venue: Lecture Theatre H (Lifts 27-28), HKUST: Abstract.
