Unification of Aeolian and Fluvial Sediment Transport Rate from Granular Physics
Thomas Pähtz, Orencio Durán
One of the physically least understood characteristics of geophysical transport of sediments along sediment surfaces is the well known experimental observation that the sediment tr…
Local Rheology Relation with Variable Yield Stress Ratio across Dry, Wet, Dense, and Dilute Granular Flows
Thomas Pähtz, Orencio Durán, David N. de Klerk +2
Dry, wet, dense, and dilute granular flows have been previously considered fundamentally different and thus described by distinct, and in many cases incompatible, rheologies. We ca…
Dissolution instability and roughening transition
P. Claudin, O. Duran, B. Andreotti
We theoretically investigate the pattern formation observed when a fluid flows over a solid substrate that can dissolve or melt. We use a turbulent mixing description that includes…
Direct numerical simulations of aeolian sand ripples
Orencio Duran, Philippe Claudin, Bruno Andreotti
Aeolian sand beds exhibit regular patterns of ripples resulting from the interaction between topography and sediment transport. Their characteristics have been so far related to re…
Numerical simulation of turbulent sediment transport, from bed load to saltation
Orencio Duran, Bruno Andreotti, Philippe Claudin
Sediment transport is studied as a function of the grain to fluid density ratio using two phase numerical sim- ulations based on a discrete element method (DEM) for particles coupl…
Minimal size of a barchan dune
Eric J. R. Parteli, Orencio Duran, Hans J. Herrmann
Barchans are dunes of high mobility which have a crescent shape and propagate under conditions of unidirectional wind. However, sand dunes only appear above a critical size, which…
