Flow and clog in a silo with oscillating exit
WebWe study the flow of elongated grains (wooden pegs of length =20 mm with circular cross section of diameter =6 and 8 mm) from a silo with a rotating bottom and a circular orifice of diameter . In the small orifice rang… WebThe present work reports an investigation into the collisional dynamics of particles in the vicinity of the outlet of a two-dimensional silo using molecular dynamics simulations. Most studies on this granular system focus in the bulk of the medium. In this region, contacts are permanent or long-lived, so continuous approximations are able to yield results for …

The rotation enhances the breakage of clogging arches, which is responsible for improving the flowability in the horizontal silo.
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.
