SIMULATIONS OF FLOW PATTERNS IN SILOS WITH A CELLULAR AUTOMATON: PART 2

Abstract

An improved cellular automaton has been used to calculate the kinematics of noncohesive granular materials during confined flow in mass and funnel flow model silos. In this model, based on a gas model of hydrodynamics, collisions and dissipation of particles were taken into account during granular flow. The model allowed for investigations of dilatant zones in granular material during silo flow.
