Akinori Awazu
TL;DR
This study explores how two inelastic spheres in a confined box exhibit segregation and phase inversion behaviors, influenced by restitution, mass ratio, and box size, revealing state transitions in a minimal granular system.
Contribution
It demonstrates that even a simple two-sphere system can exhibit complex segregation phenomena and phase inversion, highlighting fundamental granular behaviors.
Findings
Identification of two distinct segregated states
Observation of crossover between segregated states
Dependence of segregation on restitution, mass ratio, and box size
Abstract
The segregation and the phase inversion are investigated through a simple granular system which consists of only two inelastic hard spheres in a square box with an energy source. With the variation of the coefficient of restitution, the mass ratio between two spheres or the box size, we show that two types of segregated states and crossover between them are realized in such a small simple system.
