Anchoring effect of an obstacle in the silo unclogging process
Contrary to the proven beneficial role that placing an obstacle above a silo exit has in
clogging prevention, we demonstrate that, when the system is gently shaken, this passive …

Nonergodicity in silo unclogging: Broken and unbroken arches
We report an experiment on the unclogging dynamics in a two-dimensional silo submitted to
a sustained gentle vibration. We find that arches present a jerking motion where …

Competition analysis of grain flow versus clogging by means of information theory
R Caitano, AJ Ramirez-Pastor, EE Vogel, G Saravia - Granular Matter, 2024 - Springer
The different flow regimes in a two-dimensional silo with a vibrated base are studied in terms
of the usual statistical techniques and information theory. The passage of granular material …

Strategic placement of an obstacle suppresses droplet break up in the hopper flow of a microfluidic soft crystal
When granular materials, colloidal suspensions, and even animals and crowds exit through
a narrow outlet, clogs can form spontaneously when multiple particles or entities attempt to …
