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…
On buoyancy in disperse two-phase flow and its impact on the well-posedness of two-fluid models
Rui Zhu, Yulan Chen, Katharina Tholen +2
The Maxey--Riley--Gatignol equation for the flow around a sphere at low particle Reynolds number tells us that the fluid-particle interaction force decomposes into a contribution f…
Addressing bedload flux variability due to grain shape effects and experimental channel geometry
Thomas Pähtz, Yulan Chen, Jiafeng Xie +8
The study-to-study variability of bedload flux measurements in turbulent sediment transport borders an order of magnitude, even for idealized laboratory conditions. This uncertaint…
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…
