Review and implementation of CFD-DEM applied to chemical process systems
Shahab Golshan,Shahab Golshan,Rahmat Sotudeh-Gharebagh,Reza Zarghami,Navid Mostoufi,Bruno Blais,J.A.M. Kuipers +6 more
TL;DR: In this paper, the authors provide an introduction to coupled computational fluid dynamics (CFD-DEM) modeling in process engineering systems, including heat and mass transfer and long range forces, and review the major researches in simulation of two-phase processes such as drying, coating, granulation, crystallization, chemical reactions (including combustion, gasification and pyrolysis) and mixing.

An integrated workflow for resolved-particle packed bed models with complex particle shapes
TL;DR: In this article, a promising workflow for computational generation and meshing of resolved-particle randomly packed beds of arbitrary-shaped particles is described, based on an automated package that is developed for the Bullet Physics Library for packed bed generation, and on the shrink-wrap method for handling the meshing challenges of the particle contact areas.

CFD-DEM simulation of heat transfer in fluidized beds: Model verification, validation, and application
TL;DR: For a single isolated particle, the effect of overlap displacement on conduction and particle diameter/fluid velocity on convection were comprehensively studied using a CFD-DEM method coupled with heat exchange as mentioned in this paper.

TL;DR: In this paper, the gear predictor -corrector is used to calculate forces and torques in a non-equilibrium molecular dynamics simulation using Monte Carlo methods. But it is not suitable for the gear prediction problem.

Discrete numerical model for granular assemblies.
Peter Cundall,Otto D. L. Strack +1 more
TL;DR: The distinct element method as mentioned in this paper is a numerical model capable of describing the mechanical behavior of assemblies of discs and spheres and is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the objects modelled particle by particle.
