A resolved CFD-DEM coupling model for modeling two-phase fluids interaction with irregularly shaped particles

Journal of Computational Physics, 2022
In this paper, we develop a resolved coupling model to simulate interaction between two-phase fluids and irregularly shaped particles by using Computational Fluid Dynamics (CFD) and Discrete Element Method (DEM).

A Coupled CFD-DEM Simulation of Immersed Granular Collapse

2021
<p>Natural disasters normally involve the flow of polydispersed granular materials with interstitial fluid which may change the flow dramatically. Here we focus on a typical small-scale case of fluid–particle mixture flows, i.e., the immersed granular collapse using computational fluid dynamics coupled with discrete element ...

Numerical Investigations of the Extraction of Submerged Foundations by Coupled CFD-DEM

Volume 9: Offshore Geotechnics; Torgeir Moan Honoring Symposium, 2017
Offshore 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-

Coupled CFD-DEM simulation of hydrodynamic bridging at constrictions

International Journal of Multiphase Flow, 2016
This paper presents a coupled CFD-DEM approach to simulate the flow of particulate suspensions in the intermediate concentration regime where solid volume concentration is 1% < ϕ < 50%. In particular, hydrodynamic multi-particle bridging during flow through a single constriction in a rectangular channel is studied.

Coupled CFD-DEM simulation of granular LCM bridging in a fracture

Particulate Science and Technology, 2019
Developed fractures are important storage space and permeable channel in hydrocarbon reservoirs. However, they will lead to drill-in fluid loss and induce severe formation damage.

Sensitivity analysis in the modelling of debris flow with coupled CFD-DEM

2022
Due to socio-economic development and climate change, geological disasters such as landslides and floods are expected to increase. In mountainous areas, these geohazards are often caused by heavy storms. Natural disasters such as debris flows (DF) and rockfalls usually occur within natural terrain areas.
