Flow and clog in a silo with oscillating exit
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 … 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

WebMay 26, 2024 · Abstract. In this work we present experimental results of the flow and clogging of monodisperse spheres in a silo geometry, with an obstacle placed near the exit aperture. In previous work, it has been shown that the placement of an obstacle in a two-dimensional silo can suppress clogging. We extend prior work to investigate the effects … 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.
