Silo discharge of binary granular mixtures
(American Physical Society, 2017-08)
We present numerical and experimental results on the mass flow rate during the discharge of three-dimensional silos filled with a bidisperse mixture of grains of different sizes. We analyzed the influence of the ratio ...
Pattern formation in oscillatory granular flows

Dynamic transition in conveyor belt driven granular flow
(Elsevier Science Sa, 2015-03)
We consider the flow of disks of diameter d driven by a conveyor belt of dynamic friction coefficient μ through an aperture on a flat barrier. The flow rate presents two distinct regimes. At low belt velocities v the flow ...
Meios granulares e experimentos simples para a sala de aula
(Sociedade Brasileira de Física, 2008)
Nos últimos anos houve um grande aumento da atividade experimental e teórica no estudo das propriedades dos materiais granulares. Este artigo apresenta uma breve revisão da literatura sobre este tema e sugere experimentos ...

Granular flow through an aperture: Pressure and flow rate are independent
(American Physical Society, 2011-06)
We simultaneously measure the flow rate and the normal force on the base, near the outlet, during the discharge through an orifice of a dense packing of monosized disks driven by a conveyor belt. We find that the normal ...
Dynamic behavior of humid granular avalanches: Optical measurements to characterize the precursor activity
(American Physical Society, 2020-02)
Laboratory study of slope stability of granular media remains a challenge for modeling, understanding, and predicting natural hazards, such as avalanches and landslides, precursory signs of which are controlled by numerous ...
