Discrete element simulation of internal stress and flow fields in funnel flow hoppers

Newtonian dynamics simulations have been carried out for the filling and discharge of funnel flow hoppers under both plane-strain (2D) and axially-symmetric (3D) conditions using assemblies of the order of 10 4 particles. The present work follows directly from our previous discrete element simulatio...
