General model for segregation forces in flowing granular mixtures
Yifei Duan, Lu Jing, Paul B. Umbanhowar +2
Particle segregation in dense flowing size-disperse granular mixtures is driven by gravity and shear, but predicting the associated segregation force due to both effects has remain…
Segregation forces in dense granular flows: Closing the gap from single intruders to mixtures
Yifei Duan, Lu Jing, Paul B. Umbanhowar +2
Using simulations and a virtual-spring-based approach, we measure the segregation force, Fseg, over a range of size-bidisperse mixture concentrations, particle size ratios, and she…
A unified description of gravity- and kinematics-induced segregation forces in dense granular flows
Lu Jing, Julio M. Ottino, Richard M. Lueptow +1
Particle segregation is common in natural and industrial processes involving flowing granular materials. Complex, and seemingly contradictory, segregation phenomena have been obser…
Modified Archimedes' principle predicts rising and sinking of intruders in sheared granular flows
Lu Jing, Julio M. Ottino, Richard M. Lueptow +1
We computationally determine the force on single spherical intruder particles in sheared granular flows as a function of particle size, particle density, shear rate, overburden pre…
A comprehensive study of coupled LBM-DEM with immersed moving boundary
G. C. Yang, L. Jing, C. Y. Kwok +1
A systematic study is carried out on a fully resolved fluid-particle model which couples the Lattice Boltzmann Method (LBM) and the Discrete Element Method (DEM) using an immersed…
Squeeze expulsion in grain size segregation
Lu Jing, C. Y. Kwok, Y. F. Leung
Grain segregation occurs under various conditions, such as vibration, shear and mixing. In the gravity-driven shear flow, size segregation is triggered by the percolation of small…
