Grain-scale computations of barchan dunes
Nicolao Cerqueira Lima, Willian Righi Assis, Carlos Azael Alvarez +1
Barchans are crescent-shaped dunes commonly found in diverse environments and scales: from the 10-cm-long barchans found under water to the 1-km-long barchans on Mars, passing by t…
Collaborative behavior of intruders moving amid grains
Douglas Daniel de Carvalho, Erick de Moraes Franklin
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…
Contacts, motion and chain-breaking in a two-dimensional granular system displaced by an intruder
Douglas Daniel de Carvalho, Nicolao Cerqueira Lima, Erick de Moraes Franklin
We investigate numerically how the motion of an intruder within a two-dimensional granular system affects its structure and produces drag on the intruder. We made use of discrete n…
