Slipping on an Arbitrary Surface with Friction
Felipe González-Cataldo, Gonzalo Gutiérrez, Julio Yañez
The motion of a block slipping on a surface is a well studied problem for flat and circular surfaces, but the necessary conditions for the block to leave (or not) the surface deser…
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…
Simulation of grains in a vibrated U-tube without interstitial fluid
J. R. Darias, I. Sánchez, G. Gutiérrez +1
We present a computational study using Molecular Dynamics of the development of an accumulation of grains in one side of a two dimensional U-tube under vertical vibrations. Studyin…
Granular instability in a vibrated U tube
I. Sánchez, J. R. Darias, R. Paredes +2
We study experimentally the collective motion of grains inside a U shaped tube undergoing vertical oscillations, and we develop a very simple quantitative model that captures relev…
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…
