On the testing of grain shape corrections to bedload transport equations with grain-resolved numerical simulations
Yulan Chen, Orencio Durán, Thomas Pähtz
Using grain-resolved LES-DEM simulations, Zhang et al. (J. Geophys. Res. Earth Surf. 130, e2024JF007937, 2025) aimed to validate a grain-shape-corrected bedload transport equation…
The role of hydrodynamics for the spatial distribution of high-temperature hydrothermal vent-endemic fauna in the deep ocean environment
Zhiguo He, Yingzhong Lou, Haoyang Zhang +7
Active hydrothermal vents provide the surrounding submarine environment with substantial amounts of matter and energy, thus serving as important habitats for diverse megabenthic co…
Coarse-graining particulate two-phase flow
Thomas Pähtz, Yulan Chen, Rui Zhu +2
To acquire the ability to numerically study the rheology of particulate two-phase flows that lack scale separation, we present a general method to average or coarse-grain the equat…
Large Effects of Particle Size Heterogeneity on Dynamic Saltation Threshold
Wei Zhu, Xinghui Huo, Jie Zhang +4
Reliably predicting the geomorphology and climate of planetary bodies requires knowledge of the dynamic threshold wind shear velocity below which saltation transport ceases. Here w…
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…
Modeling of Breaching Due to Overtopping Flow and Waves Based on Coupled Flow and Sediment Transport
Zhiguo He, Peng Hu, Liang Zhao +2
Breaching of earthen or sandy dams/dunes by overtopping flow and waves is a complicated process with strong, unsteady flow, high sediment transport, and rapid bed changes in which…
Discrete Element Method simulations of the saturation of aeolian sand transport
Thomas Pähtz, Amir Omeradžić, Marcus V. Carneiro +2
The saturation length of aeolian sand transport (), characterizing the distance needed by wind-blown sand to adapt to changes in the wind shear, is essential for accurate mode…
