Formation of cylindrical shells via sphere packing from fluidized beds
VinÃcius Pereira da Silva Oliveira, Danilo da Silva Borges, Erick de Moraes Franklin +1
The results of a numerical investigation of fluidized beds of spherical particles in a narrow vertical cylindrical pipe, with particular attention to the spontaneous settling along…
Aggregates in fluidized beds: the effect of bonding angles on fluidization
VinÃcius Pereira da Silva Oliveira, Danilo da Silva Borges, Erick de Moraes Franklin
Fluidized beds consist of solid particles suspended in a tube by an ascending fluid. In liquids, it is not rare that particles adhere to each other, decreasing the solid-liquid con…
Role of Friction on the Formation of Confined Granular Structures
VinÃcius Pereira da S. Oliveira, Danilo S. Borges, Erick M. Franklin +1
Unstable systems of fluidized grains in a very-narrow vertical tube can auto-defluidize after some time, the settling particles forming either a glass- or crystal-like structure. W…
Resultant force on grains of a real sand dune: How to measure it?
Renato F. Miotto, Carlos A. Alvarez, Danilo S. Borges +2
Dunes are bedforms found on sandy terrains shaped by fluid flow on Earth, Mars, and other celestial bodies. Despite their prevalence, understanding dune dynamics at the grain scale…
