Abstract
In this work, smoothed particle hydrodynamics (SPH) is employed to investigate the granular flow in a rotating drum. The granular material is modeled with a μI rheology-based elastoplastic model with the Druck-Prager yield surface. The μI relation is regularized with a penalty scheme to remove the singularity in the case of zero pressure or shear rate. Two benchmark problems, including the sand column collapse and the granular mixing due to pure convection, are simulated to examine the proposed SPH method. The numerical simulations are compared with available experimental and numerical results. A series of numerical simulations are conducted to study the behavior of the granular bed in a rotating drum. It turns out the proposed SPH method is a promising tool to reveal the characteristics of flow modes, bed profile, velocity field and stress distribution.
