Experimental methods in chemical engineering: Unresolved CFD‐DEM
The Canadian Journal of Chemical Engineering, 2020AbstractCFD‐DEM combines computational fluid dynamics (CFD), which solves the equation of motion of gas or liquids, with the discrete element method (DEM), a simulation technique based on a Lagrangian description of particle motion that predicts the flow of granular matter and powders.

CFD-DEM Modelling: Clogging of Triplet Particles in a Microchannel With a Constriction
2021 IEEE 6th International Forum on Research and Technology for Society and Industry (RTSI), 2021Clogging represents an important issue in the field of chemical engineering, particularly concerning microfluidic technologies such as microreactors. This phenomenon consists in the the interruption of the flow in confined geometries due to the complete blockage of the channel cross-section. Since experiments can be expensive and difficult to implement,

CFD-DEM simulations in water channel flow
AIP Conference Proceedings, 2020On the basis of two way coupling approach numerical simulations of particle movement in water channel flow is presented. The movement of the particles is simulated by the EDEM software and the water flow is simulated by a standard k-epsilon model. Two shapes of the particles were used - spherical and oval-shaped. The flow Reynolds number was Re=27000.

CFD-DEM simulations of particulate fouling in microchannels
Chemical Engineering Journal, 2019Abstract One of the critical issues encountered when particle suspensions are made to flow in microfluidic devices is the adhesion of the suspended particles on the channel surfaces. This process, known as fouling, may lead to a progressive growth of clusters attached to the walls and, possibly, to a complete clogging of the microchannel.

Parallel CFD-DEM for Fluid-Particle Systems
Volume 3, 2004This paper presents numerical methods and parallel algorithms for modeling the fluid-particle flow in gas fluidization of multi-sized particles. This work involves combined Computational Fluid Dynamics (CFD) and Discrete Element Method (DEM) to describe continuum flow of fluids and discrete flow of solid particles, respectively.

Validation of CFD+DEM Against Measured Data
Volume 8: Ian Jordaan Honoring Symposium on Ice Engineering, 2015In this paper the author attempts to validate the ability of CFD and DEM to predict the added resistance due to brash ice. For this, a comparison is made between measured data and computational results. In addition, the paper provides details on the computational effort required.

On the Improvement of CFD-DEM Coarse Graining Predictions
Volume 1B, Symposia: Fluid Mechanics (Fundamental Issues and Perspectives; Industrial and Environmental Applications); Multiphase Flow and Systems (Multiscale Methods; Noninvasive Measurements; Numerical Methods; Heat Transfer; Performance); Transport Phenomena (Clean Energy; Mixing; Manufacturing and Materials Processing); Turbulent Flows — Issues and Perspectives; Algorithms and Applications for High Performance CFD Computation; Fluid Power; Fluid Dynamics of Wind Energy; Marine Hydrodynamics, 2016Discrete Element Method (DEM) coupled to Computational Fluid Mechanics (CFD) is a powerful tool for simulating complex multiphase flows. The cost of this Eulerian-Lagrangian description, however, increases with the increase of the number of particles ∼O(Np) which limit its use in natural and industrial scale systems.
