Resumen
Certain spatial distributions of water inside partially filled containers can significantly reduce the bounce of the container. In experiments with containers filled to a volume fraction φ, we show that rotation offers control and high efficiency in setting such distributions and, consequently, in altering bounce markedly. High-speed imaging evidences the physics of the phenomenon and reveals a rich sequence of fluid-dynamics processes, which we translate into a model that captures our overall experimental findings. © 2023 authors.

Stability of a tilted granular monolayer: How many spheres can we pick before the collapse (2024)
Rojas, Eduardo; Alarcón, Héctor; Salinas, Vicente; Castillo, Gustavo; Gutiérrez, Pablo (American Physical Society, 2023)The triggering of avalanches is investigated using discrete element simulations for a process of random extraction of spheres. A monolayer, formed by identical spheres in a hexagonal configuration, is placed on a tilted ... -

Triggering avalanches by transverse perturbations in a rotating drum (2021)
Salinas, Vicente; Quininao, Cristóbal; González, Sebastián; Castillo, Gustavo (NLM (Medline), 2021-07-06)We study the role of small-scale perturbations in the onset of avalanches in a rotating drum in the stick-slip regime. By vibrating the system along the axis of rotation with an amplitude orders of magnitude smaller than ... -
