Continuum theory for dense gas-solid flow: A state-of-the-art review
TL;DR: In this paper, the Navier-Stokes order continuum theory is used for CFD simulation of the hydrodynamics of gas-solid fluidization, without taking the effects of heat and mass transfer as well as chemical reactions into consideration.

Applicability of a coarse-grained CFD–DEM model on dense medium cyclone
TL;DR: In this paper, a coarse-grained (CG) model is developed to model the swirling multiphase flow in a dense medium cyclone (DMC) and the error caused by the CG concept is quantified by carrying out controlled numerical calculations to directly compare the simulated results between a standard CFD-DEM model and a CG CFD−DEM model.

A Methodical Calibration Procedure for Discrete Element Models
Michael Rackl,Kevin J. Hanley +1 more
TL;DR: In this paper, a methodical calibration approach based on Latin hypercube sampling and Kriging meta-models was proposed to calculate the angle of repose and bulk density for spherical glass beads.

Discrete simulation of granular and particle-fluid flows: from fundamental study to engineering application
TL;DR: This review discusses the enabling methods and technologies for multiscale discrete simulations (MSDS), and concludes that with these developments, MSDS could soon become, among others, a mainstream simulation approach in chemical engineering which enables VPE.
Journal ArticleDOI
Discrete element simulation for the evaluation of solid mixing in an industrial blender
TL;DR: It is illustrated that the total amount of powder affected the mixing efficiency of the twin-screw kneader, and the numerical simulation could clarify the mixing mechanism behind observed phenomena.

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.

Discrete particle simulation of two-dimensional fluidized bed
TL;DR: In this paper, Cundall's Distinct Element Method (P.A.Cundall and O.L. Strack, 1979) is used to model contact forces between particles.
