Three-dimensional simulation of a solid–liquid flow by the DEM–SPH method

Three-dimensional simulation of gas–solid–liquid flows using the DEM–VOF method

“…Although the classical gas-liquid dam break has been well studied in last decades which dates back to the experiment of Martin and Moyce (1952), its three-phase version containing a particle bed has not been thoroughly discussed. Among limited literatures, some authors reported numerical results by using Lagrangian particle methods ignoring the gas phase motion, see Guo and Morita (2013) and Sun et al (2013). In this test, we simulate a dam break flow involving fully gas-solidliquid three-phase dynamics and perform experiments for validation.…”

Discrete element simulation for the evaluation of solid mixing in an industrial blender

“…Very recently, new Lagrangian-Lagrangian approaches have been developed to simulate solid-liquid flows involving free surfaces, where the DEM is coupled with a Lagrangian CFD approach such as the smoothed particle hydrodynamics (SPH) method [22] or the moving-particle semi-implicit (MPS) method [23]. The Lagrangian-Lagrangian approach is thus referred to as the DEM-MPS method [24][25][26]or the DEM-SPH method [27]. These methods can be used to simulate complex solid-fluid coupling problems such as those of wet ball mills.…”

A Particle Element Approach for Modelling the 3D Printing Process of Fibre Reinforced Polymer Composites

“…It mainly depends on both the relative resin flow velocity and the local density of neighbouring DEM particles. For a single DEM particle, the drag force can be formulated as follows [23]:…”
