Behavior of grains in contact with the wall of a silo during the initial instants of a discharge-driven collapse
C. Colonnello, L. I. Reyes, E. Clément +1
We study experimentally gravity-driven granular discharges of laboratory scale silos, during the initial instants of the discharge. We investigate deformable wall silos around thei…
Characterization of invariant patterns in a slowly rotated granular tumbler
Leonardo Reyes, Oscar Pérez, Claudia Colonnello +4
We report experimental results of the pattern developed by a mixture of two types of grains in a triangular rotating tumbler operating in the avalanche regime. At the centroid of t…
Random loose packing and an order parameter for the parking lot model
K. Hernández, L. I. Reyes
We have obtained the random loose packing fraction of the parking lot model (PLM) by taking the limit of infinite compactivity in the two-variable statistical description of Tarjus…
A mechanism for air induced fluidization in vibrated granular beds
L. I. Reyes, I. Sánchez, G. Gutiérrez
We present a new mechanism for the fluidization of a vibrated granular bed in the presence of interstitial air. We show that the air flow induced across the bed, as the gap in the…
Simple model for reverse buoyancy in a vibrated granular system
G. Gutiérrez, O. Pozo, L. I. Reyes +3
Large objects, immersed in a homogeneous granular system, migrate when subjected to vibrations. Under certain conditions large heavy objects rise and similar light ones sink to the…
