Mechanisms leading to axial segregation of bidisperse particles in rotating tumblers
Umberto d'Ortona, Richard Lueptow, Nathalie Thomas
The origin of segregated axial bands for size-bidisperse particles in long rotating tumblers is a long-standing question in granular flows and a problem of both fundamental and pra…
Percolation of a rod-like particle in a static bed of spheres: trapping and passing
Juan C. Petit, Julio M. Ottino, Richard M. Lueptow +1
We numerically investigate percolation of independent frictionless glued-sphere rod-like particles under gravity through a disordered static bed of larger spheres. We identify two…
Percolation of a cohesive fine particle in a static bed
Jizhi Zhang, Qiong Zhang, Julio M. Ottino +2
Percolation of fine particles (fines) in a static bed of larger particles is central to many industrial and natural processes. Non-cohesive fines either pass through the bed or bec…
