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…
Designing non-segregating granular mixtures
Yifei Duan, Paul B. Umbanhowar, Richard M. Lueptow
In bidisperse particle mixtures varying in size or density alone, large particles rise (driven by percolation) and heavy particles sink (driven by buoyancy). When the two particle…
