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.

Numerical Investigations of the Extraction of Submerged Foundations by Coupled CFD-DEM
Volume 9: Offshore Geotechnics; Torgeir Moan Honoring Symposium, 2017Offshore structures are founded on submerged foundations. The excavation of submerged foundations in the sea bed is a difficult task to accomplish when it comes to the decommissioning of these offshore structures. The extraction resistance is a lot higher than the pressure acting on the structure due to hydrostatic pressure, earth pressure and its self-

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.

Accounting for Particle Morphology in CFD-DEM Modelling
Proceedings of the 2024 UK Association for Computational Mechanics ConferenceIn this study, the drag force acting on real irregular particles with various morphologies belonging to the four shape categories of the Zingg chart is estimated using the empirical models proposed in literature and the results are compared to the drag force obtained through computational fluid dynamics (CFD).

CFD-DEM MODELLING AND ANALYSIS OF HYDRAULIC CONVEYING
2020In this thesis work, a coupling method of computational fluid dynamics (CFD) and discrete element method (DEM) is successfully applied to simulate the process of hydraulic conveying. The fundamentals governing the complex liquid-solid flow and performance of hydraulic conveying are systematically analysed in terms of particle-particle, particle-fluid ...
