Sediment transport simulations face the challenge of accounting for vastly different scales in
space and time that cannot be tackled by a unifying approach. Instead, processes are …

Relationships and feedback between airflow dynamics, sand transport and underlying
surface characteristics play significant roles in the formation and evolution of aeolian …

The flow field and the sediment motion generated over a rippled bed by a uniform and
oscillating pressure gradient are evaluated by means of a direct numerical simulation of …

We present results of coupled direct numerical simulations between flow and a deformable
bed in a horizontally periodic, turbulent open channel at a shear Reynolds number of Re τ …

Barchan dunes are three‐dimensional, crescent‐shaped bedforms found in regions of
unidirectional flow and limited sediment supply, and while most commonly associated with …

We present results from open-channel, Euler–Lagrange (EL) simulations of turbulent flow
over an erodible particle bed at a shear Reynolds number of. Upon space and time …

Coupled bed‐flow direct numerical simulations investigating the early stages of pattern
formation and bedform (ripple) interactions were examined in a previous paper (Part 1) …

We use a recently-developed, turbulence-informed physics-based model to study frost
buildup over a flat plate subjected to turbulent flow. The plate temperature is held fixed but …

We carried out high‐resolution Large Eddy Simulations to study the three‐dimensional
hydrodynamic characteristics over regular and irregular wave‐generated ripples. Two types …

Sand dunes, which arise spontaneously due to the dynamical interplay between a
sedimentary interface and a fluid flow, are one of the most famous examples of emergence …
