TL;DR
This study investigates how a bi-disperse granular gas exhibits competitive clustering behavior in a compartmentalized system, with clustering direction depending on shaking strength, explained by a flux model.
Contribution
It introduces a flux model that quantitatively explains the competitive clustering phenomena in bi-disperse granular gases.
Findings
Clustering direction depends on shaking strength.
Flux model accurately predicts clustering behavior.
Experimental results match theoretical predictions.
Abstract
A bi-disperse granular gas in a compartmentalized system is experimentally found to cluster competitively: Depending on the shaking strength, the clustering can be directed either towards the compartment initially containing mainly small particles, or to the one containing mainly large particles. The experimental observations are quantitatively explained within a flux model.
