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…
