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…
Evolving dunes under flow reversals: from an initial heap toward an inverted dune
Willian Righi Assis, Erick de Moraes Franklin, Nathalie Vriend
Sand dunes are ubiquitous in nature, and are found in abundance on Earth and other planetary environments. One of the most common types are crescent-shaped dunes known as barchans,…
Miniaturized gas-solid fluidized beds
Fernando David Cúñez Benalcázar, Erick de Moraes Franklin
Fluidized beds are suspensions of grains by ascending fluids in tubes, and are commonly used in industry given their high rates of mass and heat transfers between the solids and fl…
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…
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…
