Collaborative behavior of intruders moving amid grains

DD Carvalho, EM Franklin - Physics of Fluids, 2022 - pubs.aip.org
We investigate the motion of groups of intruders in a two-dimensional granular system by
using discrete numerical simulations. By imposing either a constant velocity or a thrusting …

R Basak, R Kozlowski, LA Pugnaloni, M Kramar… - Physical Review E, 2023 - APS
In quasi-two-dimensional experiments with photoelastic particles confined to an annular
region, an intruder constrained to move in a circular path halfway between the annular walls …

Controlled stigmergy in quasi-one-dimensional active particle systems

G Bánó, C Slabý, A Strejčková, Z Tomori, A Hovan… - Physical Review E, 2024 - APS
In quasi-one-dimensional circularly symmetric systems of active particles, experiments and
simulations reveal an indirect interplay between particles and environmental drag effects …

Drag reduction during the side-by-side motion of a pair of intruders in a granular medium

DD Carvalho, Y Bertho, A Seguin, EM Franklin… - Physical Review …, 2024 - APS
When several intruders move in a granular medium, coupling effects are observed, the
motion of one intruder affecting that of others. In this paper, we investigate experimentally …
