How particle shape affects granular segregation in industrial and geophysical flows
Industrial and environmental granular flows commonly exhibit a phenomenon known as
“granular segregation,” in which grains separate according to physical characteristics (size …

Particle size segregation in granular mass flows with different ambient fluids
Size segregation, which is a robust feature of sheared granular mixtures and geophysical
mass flow deposits, is found to diminish in the presence of a viscous fluid. We study this …

Drag force in granular shear flows: regimes, scaling laws and implications for segregation
The drag force on a spherical intruder in dense granular shear flows is studied using
discrete element method simulations. Three regimes of the intruder dynamics are observed …
