Initial Instabilities of a Granular Bed Sheared by a Turbulent Liquid Flow: Length-Scale Determination
(Abcm Brazilian Soc Mechanical Sciences & EngineeringRio De Janeiro RjBrasil, 2010)
Segregation in a model system for tapped wet disks in two dimensions
(Springer, 2015-11-30)
The problem of segregation of mixtures in a column of wet disks subjected to tapping is studied through a simple model that simulates, through a pseudo-dynamics algorithm, the formation of the packing and the successive ...
Dynamics of a grain-scale intruder in a two-dimensional granular medium with and without basal friction
(American Physical Society, 2019-09-25)
We report on a series of experiments in which a grain-sized intruder is pushed by a spring through a two-dimensional granular material composed of photoelastic disks in a Couette geometry. We study the intruder dynamics ...
A high-speed tracking algorithm for dense granular media
(Elsevier B.V., 2018)
Many fields of study, including medical imaging, granular physics, colloidal physics, and active matter,
require the precise identification and tracking of particle-like objects in images. While many algorithms
exist to ...
Characterization of the energy bursts in vibrated shallow granular systems
(2012)
We study the recently reported energy bursts that take place in a granular system confined to a vertically vibrated shallow box containing two types of grains of equal size but different mass (Rivas in Phys Rev Lett ...
A High-Speed Tracking Algorithm For Dense Granular Media
(2018)
Many fields of study, including medical imaging, granular physics, colloidal physics, and active matter, require the precise identification and tracking of particle-like objects in images. While many algorithms exist to ...
Enhancement of the flow of vibrated grains through narrow apertures by addition of small particles
(American Physical Society, 2021-03)
We analyze the flow and clogging of circular grains passing through a small aperture under vibration in two dimensions. Via discrete element method simulations, we show that when grains smaller than the original ones are ...
van der Waals-like transition in fluidized granular matter: hydrodynamic description
(Descalzi, O.Martinez, J.Rica, S.Kluwer Academic Publishers, 2002)
A phase separation of fluidized granular matter is presented. Molecular dynamics simulations of grain system, in two spatial dimensions, with a vibrating wall and without gravity exhibit appearance, coagulation, and ...
