Intruder in a two-dimensional granular system: effects of dynamic and static basal friction on stick-slip and clogging dynamics
(2019-10-15)
We discuss the results of simulations of an intruder pulled through a two-dimensional granular system
by a spring, using a model designed to lend insight into the experimental findings described by Kozlowski
et al. [Phys. ...
Two approaches to quantification of force networks in particulate systems
(2021-02-24)
The interactions between particles in particulate systems are organized in ‘force networks’,
mesoscale features that bridge between the particle scale and the scale of the system as a whole.
While such networks are known ...
On the use of magnetic particles to enhance the flow of vibrated grains through narrow apertures
(2021-06-28)
The ow of grains through narrow apertures posses an extraordinary challenge: clogging. Strategies to alleviate the effect of clogging, such as the use of external vibration, are always part of the design of machinery for ...
Self-assembly of self-propelled magnetic grains
(2021)
In this work, we study bidisperse mixtures of self-propelled magnetic particles of di erent shapes
via discrete element method simulations. We show how these particles self-assemble into clusters and how these clusters ...
Stability and conductivity of proppant packs during flowback in unconventional reservoirs: a CFD–DEM simulation study
(Elsevier B.V., 2021)
We present simulations using a coupled Computational Fluid Dynamics–Discrete Element Method (CFD–DEM)
approach for a slurry of millimeter-sized particles in water which is squeezed between two walls and then made
flow ...
Universal features of the stick-slip dynamics of an intruder moving through a confined granular medium
(2022-04-21)
Experiments and simulations of an intruder dragged by a spring through a two-dimensional annulus of granular
material exhibit robust force fluctuations. At low packing fractions (φ < φ0), the intruder clears an open ...
