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…

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…

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,…

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…

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…

Register-Like Storage Block Used as Cluster Buffers, Histograms, and Hough Transform Accumulators for HEP Trigger Systems

Jinyuan Wu

In high energy physics experiment trigger systems, block memories are utilized for various purposes, especially in binned searching algorithms. In these algorithms, the storages ar…

Morphodynamics of barchan-barchan interactions investigated at the grain scale

Willian Righi Assis, Erick de Moraes Franklin

Corridors of size-selected crescent-shaped dunes, known as barchans, are commonly found in water, air, and other planetary environments. The growth of barchans results from the int…

A comprehensive picture for binary interactions of subaqueous barchans

Willian Righi Assis, Erick de Moraes Franklin

We investigate experimentally the short-range interactions occurring between two subaqueous barchans. The experiments were conducted in a water channel of transparent material wher…
