A hybrid LBM-DEM framework with an improved immersed moving boundary method for modelling complex particle-liquid flows involving adhesive particles
Wenwei Liu, Chuan-Yu Wu
This paper presents an improved immersed moving boundary model (IBM) for solving complex fluid-particle interactions in a coupled lattice Boltzmann method (LBM) and an adhesive dis…
Unifying size-topology relations in random packings of dry adhesive polydisperse spheres
Wenwei Liu, Sheng Chen, Chuan-yu Wu +1
We study the size-topology relations in random packings of dry adhesive polydisperse microspheres with Gaussian and lognormal size distributions through a geometric tessellation. W…
A fast adhesive discrete element method for random packings of fine particles
Sheng Chen, Wenwei Liu, Shuiqing Li
Introducing a reduced particle stiffness in discrete element method (DEM) allows for bigger time steps and therefore fewer total iterations in a simulation. Although this approach…
High-resolution of particle contacts via fluorophore exclusion in deep-imaging of jammed colloidal packings
Eru Kyeyune-Nyombi, Flaviano Morone, Wenwei Liu +3
Understanding the structural properties of random packings of jammed colloids requires an unprecedented high-resolution determination of the contact network providing mechanical st…
Equation of state for random sphere packing with arbitrary adhesion and friction
Wenwei Liu, Yuliang Jin, Sheng Chen +2
We systematically generate a large set of random micro-particle packings over a wide range of adhesion and friction by means of adhesive contact dynamics simulation. The ensemble o…
Computer simulation of random loose packings of micro-particles in presence of adhesion and friction
Wenwei Liu, Shuiqing Li, Sheng Chen
With a novel 3D discrete-element method specially developed with adhesive contact mechanics, random loose packings of uniform spherical micron-sized particles are fully investigate…
Effect of long-range repulsive Coulomb interactions on packing structure of adhesive particles
Sheng Chen, Shuiqing Li, Wenwei Liu +1
The packing of charged micron-sized particles was investigated using discrete element simulations based on adhesive contact dynamic model. The formation process and the final obtai…
Adhesive Loose Packings of Small Particles
Wenwei Liu, Shuiqing Li, Adrian Baule +1
We explore adhesive loose packings of dry small spherical particles of micrometer size using 3D discrete-element simulations with adhesive contact mechanics. A dimensionless adhesi…
