Directional Cluster Migration Driven by Escape-Rate Asymmetry in Multi-Compartment Granular Systems
Kai Kono, Hiroyuki Ebata, Shio Inagaki
Granular materials are inherently out-of-equilibrium systems due to energy dissipation through inelastic collisions and friction. When driven by mechanical agitation such as vibrat…
Convection of mono-disperse particles in a highly filled rotating cylinder
Shoichi Yoneta, Hiroyuki Ebata, Shio Inagaki
We investigate the occurrence of spontaneous convection in a coaxial cylinder highly filled with mono-disperse spheres. To analyze the flow field non-invasively, initial pulses con…
Segregation patterns in rotating cylinders determined by the size difference, density ratio, and cylinder diameter
Kurumi Kondo, Hiroyuki Ebata, Shio Inagaki
Granular materials often segregate under mechanical agitation, which differs from the expectation of mixing. It is well known that a bidisperse mixture of granular materials in a p…
Self-replicating segregation patterns in horizontally vibrated binary mixture of granules
Hiroyuki Ebata, Shio Inagaki
When granular mixtures of different sizes are fluidized, each species spontaneously separates and condenses to form patterns. Although granular segregation has been extensively stu…
History dependence of mechanical properties in granular systems
Shio Inagaki, Michio Otuski, Shin-ichi Sasa
We study the history dependence of the mechanical properties of granular media by numerical simulations. We perform a compaction of frictional disk packings in a two-dimensional sy…
Reorganization of a 2D disordered granular medium due to a small local cyclic perturbation
E. Kolb, C. Goldenberg, S. Inagaki +1
We measure experimentally the rearrangements due to a small localized cyclic displacement applied to a packing of rigid grains under gravity in a 2D geometry. We analyze the evolut…
