Mixing and transport from combined stretching-and-folding and cutting-and-shuffling
Lachlan D. Smith, Paul B. Umbanhowar, Julio M. Ottino +1
While structures and bifurcations controlling tracer particle transport and mixing have been studied extensively for systems with only stretching-and-folding, and to a lesser exten…
Transient response in granular quasi-2D bounded heap flow
Hongyi Xiao, Julio M. Ottino, Richard M. Lueptow +1
We study the transition between steady flows of non-cohesive granular materials in quasi-2D bounded heaps by suddenly changing the feed rate. In both experiments and simulations, t…
Persistent structures in a 3D dynamical system with solid and fluid regions
Zafir Zaman, Mengqi Yu, Paul P. Park +3
Remarkably persistent mixing and non-mixing regions (islands) are observed to coexist in a three-dimensional dynamical system where randomness is expected. The track of an x-ray op…
