TLDR
The results demonstrate that the DPS–CFD approach can generate the stagnant zone without global assumptions or arbitrary treatments, and confirms that increasing gas flow rate can increase the size of the stagnant Zone, and in particular changes the solid flow pattern in the furnace shaft.About:

Experimental and DEM study of segregation of ternary size particles in a blast furnace top bunker model
Yaowei Yu,Henrik Saxén +1 more
TL;DR: In this paper, size segregation of ternary size pellets during the discharging process of a hopper model through experiments and simulations is investigated, and the results show that even though many factors affect the extent of size segregation during discharging, the most important factors are the filling method, diameter ratio of fine to coarse, wall-particle static and rolling friction, interparticle rolling friction as well as mass fraction of fine particles.

CFD-DEM simulation of material motion in air-and-screen cleaning device
TL;DR: In this paper, a numerical study of the gas-solid flow in an air-and-screen cleaning shoe is carried out by use of the combined Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD) model where the motion of discrete particles phase is obtained by DEM which applies EDEM software and the flow of continuum fluid by the traditional CFD which solves the Navier-Stokes equations at a computational cell scale.

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 particulate systems: Theoretical developments
TL;DR: This paper reviews the work in this area with special reference to the discrete element method and associated theoretical developments, and covers three important aspects: models for the calculation of the particle–particle and particle–fluid interaction forces, coupling of discrete elements method with computational fluid dynamics to describe particle-fluid flow, and the theories for linking discrete to continuum modelling.
