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…
Segregation models for density-bidisperse granular flows
Yifei Duan, Paul B. Umbanhowar, Julio M. Ottino +1
Individual constituent balance equations are often used to derive expressions for species-specific segregation velocities in flows of dense granular mixtures. We propose a semiempi…
Pattern formation in a fully-3D segregating granular flow
Mengqi Yu, Paul B. Umbanhowar, Julio M. Ottino +1
Segregation patterns of size-bidisperse particle mixtures in a fully-three-dimensional flow produced by alternately rotating a spherical tumbler about two perpendicular axes are st…
