Formation of cylindrical shells via sphere packing from fluidized beds
Vinícius 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
Vinícius 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…
Barchans interacting with dune-size obstacles: details of the fluid flow and motion of grains
Nicolao Cerqueira Lima, Willian Righi Assis, Danilo da Silva Borges +1
We investigate details of the interaction of subaqueous barchans with dune-size obstacles by carrying out numerical simulations where the fluid is solved at the grain scale and the…
Role of Friction on the Formation of Confined Granular Structures
Vinícius 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…
On the effect of two-direction seasonal flows on barchans and the origin of occluded dunes
Willian Righi Assis, Danilo da Silva Borges, Erick de Moraes Franklin
We inquire into the morphodynamics of barchans under seasonal flows. For that, we carried out grain-scale numerical computations of a subaqueous barchan exposed to two-directional…
Dataset of turbulent flow over interacting barchan dunes
Jimmy Gabriel Alvarez, Danilo da Silva Borges, Erick de Moraes Franklin
Barchans are dunes commonly found in dune fields on Earth, Mars and other celestial bodies, where they can interact with each other. This article concerns experimental data for the…
Crystallization and refluidization in very-narrow fluidized beds
Vinícius Pereira da Silva Oliveira, Danilo da Silva Borges, Erick de Moraes Franklin
Fluidization of solid particles by an ascending fluid is frequent in industry because of the high rates of mass and heat transfers achieved. However, in some cases blockages occur…
Barchan dunes cruising dune-size obstacles
Willian Righi Assis, Danilo da Silva Borges, Erick de Moraes Franklin
We investigate the behavior of subaqueous barchans reaching dune-size obstacles by carrying out experiments where we varied the obstacle shape and size, the flow strength, and the…
