Retreat to advance: self-blocking enables efficient mineral replacement
Agnieszka Budek, Tomasz Szawełło, Vaughan Voller +1
Mineral replacement reactions under advective flow often suffer from severe spatial inefficiency: dissolution causes the flow to self-focus into a few dominant wormholes that bypas…
Structural barriers to complete homogenization and wormholing in dissolving porous and fractured rocks
Tomasz Szawełło, Jeffrey D. Hyman, Peter K. Kang +1
Dissolution in porous media and fractured rocks alters both the chemical composition of the fluid and the physical properties of the solid. Depending on system conditions, reactive…
When barchan dunes move over craters
Paulo Vitor Ribeiro Plácido, Danilo da Silva Borges, Willian Righi Assis +1
We investigate the possible outcomes of a subaqueous barchan moving over a crater-like depression in the bed. For that, we carried out experiments where we varied the dune size, cr…
Resolvent model-based analyses of coherent structures in Langmuir turbulence
Anqing Xuan, Lian Shen
We present an analysis of the coherent structures in Langmuir turbulence, a state of the ocean surface boundary layer driven by the interactions between water waves and wind-induce…
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,…
