Resonance-induced acceleration of the RBNE-BNE segregation inversion of granular mixtures
Yufei Shao, Anghao Li, Zaizheng Wang +2
This paper presents the experiments and simulations on the resonance-induced acceleration of the reverse Brazil nut effect (RBNE)-Brazil nut effect (BNE) segregation inversion of b…
Occurrence of gradual resonance in a finite-length granular chain driven by harmonic vibration
Tengfei Jiao, Shutian Zhang, Min Sun +1
This study presents numerical simulations of the resonance of a finite-length granular chain of dissipative grains driven by a harmonically vibrated tube. Multiple gradual resonant…
Influence of grain bidispersity on dense granular flow in a two dimensional hopper
Decai Huang
Discrete element method is conducted to investigate the bidisperse dense granular flow having big and small grains in a two dimensional hopper. A half-circular dynamical force arch…
Rectification Effect on Solitary Waves in the Symmetric Y-shaped Granular Chain
Xingyi Liu, Tengfei Jiao, Jiaye Su +3
The rectification effect on the propagation of solitary waves in the symmetric Y-shaped granular chain is numerically investigated in this Letter. A heterojunction with mass mismat…
Ring-like spin segregation of binary mixtures in a high-velocity rotating drum
Decai Huang, Ming Lu, Gang Sun +4
We present molecular dynamics simulations on the segregation of binary mixtures in a high-velocity rotating drum. Depending on the ratio of particle's radius and density, the ring-…
