Cratering by the oblique impact of a spinning projectile
Douglas Daniel de Carvalho, Erick de Moraes Franklin
We investigate the roles of spin and packing fraction on the dynamics of cratering when a solid projectile impacts a granular bed at different incident angles. For that, we carried…
Roles of packing fraction, microscopic friction and projectile spin in cratering by impact
Douglas Daniel de Carvalho, Nicolao Cerqueira Lima, Erick de Moraes Franklin
From small seeds falling from trees to asteroids colliding with planets and moons, the impact of projectiles onto granular targets occurs in nature at different scales. In this pap…
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…
Plug regime in water fluidized beds in very narrow tubes
Fernando David Cúñez Benalcázar, Erick de Moraes Franklin
The dynamics of granular plugs in water fluidized beds in narrow tubes is investigated here both experimentally and numerically. The fluidized beds were formed in a 25.4 mm-ID tube…
Role of transverse displacements in the formation of subaqueous barchan dunes
Erick M. Franklin, Carlos A. Alvarez
Crescentic shape dunes, known as barchan dunes, are formed by the action of a fluid flow on a granular bed. These bedforms are common in many environments, existing under water or…
