Turbulence in the atmospheric surface layer, especially in deserts and semi-arid regions,
significantly affects sand movement. In unstable stratification, turbulence exhibits complex …

Particle entrainment into a turbulent boundary layer flow is a phenomenon of great
importance to many environmental and industrial processes. This paper introduces a …

Sediment transport over an erodible sediment bed is studied by particle resolved
simulations with a hybrid parallel approach. To overcome the challenges of load imbalance …

Desert dust accounts for a substantial fraction of the total atmospheric aerosol loading. It
produces important impacts on the Earth system due to its nutrient content and interactions …

Abstract In this paper, Large Eddy Simulation (LES) of turbulence and Lagrangian model of
sand particle motion are adopted to study the characteristics of wind-blown sand flow for …

The influence of the atmospheric boundary layer (ABL) stability on dust emitted from
saltation is usually neglected. This has been challenged by two recent studies which …

The characteristics of wind-blown sand have mainly been derived from steady and
continuous sediment transport studies. However, aeolian sand transport exhibits …

Surface shear stresses produced by wind and particle collision play a key role in
aerodynamic entrainment and splash processes. The fluid shear stress at the surface during …

Spanwise heterogeneity in surface roughness generates secondary mean flows in a rough-
wall turbulent boundary layer. This study investigates the influence of roughness spanwise …

Desert dust plays an important role in several components of the Earth system, mainly due to
its nutrient content and interactions with radiation and clouds. Nevertheless, the airborne …
