Clogging-flowing transition of granular media in a two-dimensional vertical pipe
Abstract
We experimentally and numerically investigate the clogging behavior of granular materials in a two-dimensional vertical pipe. The nonmonotonicity of the clogging probability found in a cylindrical vertical pipe [López et al., Phys. Rev. E 102, 010902(R) (2020)2470-004510.1103/PhysRevE.102.010902] is also observed in the two-dimensional case. We numerically demonstrate that the clogging probability strongly correlates with the friction coefficient μ in addition to the pipe-to-particle diameter ratio D/d. We thus construct a clogging-flowing D/d-μ phase diagram within the 2
