Internal Waves Control Bulk Flow in Silos
David Luce, Adrien Gans, Nicolas Vandewalle +1
We experimentally measure paticle acceleration within the bulk during the discharge of a granular silo. We highlight the existence of a deceleration wave emerging at the outlet lev…

Rheological Parameter Identification in Granular Materials Using Physics-Informed Neural Networks
Barbara Baldoni, Mickaël Delcey, Yoann Cheny +3
Physics-Informed Neural Networks (PINNs) have recently emerged as a promising tool for fluid dynamics, particularly for flow reconstruction and parameter identification. In the con…

Structural Order Drives Diffusion in a Granular Packing
David Luce, Adrien Gans, Sébastien Kiesgen de Richter +1
We investigate how structural ordering, i.e. crystallization, affects the flow of bidisperse granular materials in a quasi-two-dimensional silo. By systematically varying the mass…
