Designing minimally-segregating granular mixtures for gravity-driven surface flows
Yifei Duan, Jack Peckham, Paul B. Umbanhowar +2
In dense flowing bidisperse particle mixtures varying in size or density alone, smaller particles sink (driven by percolation) and lighter particles rise (driven by buoyancy). But…

Modeling Stratified Segregation in Periodically Driven Granular Heap Flow
Hongyi Xiao, Zhekai Deng, Julio M. Ottino +2
We present a continuum approach to model segregation of size-bidisperse granular materials in unsteady bounded heap flow as a prototype for modeling segregation in other time varyi…

Granular impact and the critical packing state
Paul Umbanhowar, Daniel I. Goldman
Impact dynamics during collisions of spheres with granular media reveal a pronounced and non-trivial dependence on volume fraction ϕ. Post impact crater morphology identifies the c…
