Granular segregation across flow geometries: a closure model for the particle segregation velocity
Yifei Duan, Lu Jing, Paul B. Umbanhowar +2
Predicting particle segregation has remained challenging due to the lack of a general model for the segregation velocity that is applicable across a range of granular flow geometri…

Basal layer of granular flow down smooth and rough inclines: kinematics, slip laws and rheology
Teng Wang, Lu Jing, Fiona C. Y. Kwok +3
Granular flow down an inclined plane is ubiquitous in geophysical and industrial applications. On rough inclines, the flow exhibits Bagnold's velocity profile and follows the so-ca…

Enhancing semi-resolved CFD-DEM for dilute to dense particle-fluid systems: A point cloud based, two-step mapping strategy via coarse graining
Yuxiang Liu, Lu Jing, Xudong Fu +1
Computational fluid dynamics and discrete element method (CFD-DEM) coupling is an efficient and powerful tool to simulate particle-fluid systems. However, current volume-averaged C…
