Collision dynamics in fluidised bed granulators: A DEM-CFD study
TL;DR: In this article, the fluid, particle and collision dynamics inside a fluidized bed granulator are described in detail using coupled DEM-CFD simulations, and three different granulator configurations are compared in terms of their particle-particle interactions, using criteria such as the average particle velocity, angular velocity, average particleparticle and particle-wall collision velocity and the collision frequency.

SediFoam: A general-purpose, open-source CFD–DEM solver for particle-laden flow with emphasis on sediment transport
TL;DR: The development of a three-dimensional, massively parallel, and open-source CFD–DEM solver SediFoam is detailed, built based onopen-source solvers OpenFOAM and LAMMPS, and the parallel efficiency tests show that the scalability of SediBoat is satisfactory in the simulations using up to O ( 10 7 ) particles.

Surface energy and the contact of elastic solids
TL;DR: In this paper, the influence of surface energy on the contact between elastic solids is discussed and an analytical model for its effect upon the contact size and the force of adhesion between two lightly loaded spherical solid surfaces is presented.
