Barchan-barchan and barchan-obstacle interactions: insights from grain-scale studies
Erick de Moraes Franklin, Willian Righi Assis, Danilo da Silva Borges +1
Sand dunes are bedforms that grow due to the action of a fluid flow over a sand bed or pile. Whenever the fluid flow is mainly in one direction and the availability of sand is limi…
Undulatory forcing of an intruder through granular media: effects of frequency and packing fraction
Douglas Daniel de Carvalho, Erick de Moraes Franklin
We investigate the motion amid grains of an intruder undergoing an imposed force that oscillates with a given frequency. For that, we made use of discrete numerical simulations whe…
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…
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…
Barchan-barchan dune repulsion investigated at the grain scale
Nicolao Cerqueira Lima, Willian Righi Assis, Carlos Azael Alvarez +1
Barchans are eolian dunes of crescent shape found on Earth, Mars and other celestial bodies. Among the different types of barchan-barchan interaction, there is one, known as chasin…
Detection and tracking of barchan dunes using Artificial Intelligence
Esteban Andrés Cúñez Benalcázar, Erick de Moraes Franklin
Barchans are crescent-shape dunes ubiquitous on Earth and other celestial bodies, which are organized in barchan fields where they interact with each other. Over the last decades,…
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…
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…
