Mobility of bidisperse mixtures during bedload transport
Rémi Chassagne, Raphaël Maurin, Julien Chauchat +1
The flow of segregated bidisperse assemblies of particles is of major importance for geophysical flows and bedload transport in particular. In the present paper, the mobility of bi…
Bridging the gap between particle-scale forces and continuum modelling of size segregation: application to bedload transport
Hugo Rousseau, Rémi Chassagne, Julien Chauchat +2
Gravity-driven size segregation is important in mountain streams where a wide range of grain sizes are transported as bedload. More particularly, vertical size segregation is a mul…
Grain size segregation during bedload transport on steep slopes
Rémi Chassagne, Raphaël Maurin, Julien Chauchat +2
Size segregation in bedload transport is studied numerically with a coupled fluid-discrete element model. Starting from an initial deposit of small spherical particles on top of a…
Revisiting slope influence in turbulent bedload transport: consequences for vertical flow structure and transport rate scaling
Raphael Maurin, Julien Chauchat, Philippe Frey
Gravity-driven turbulent bedload transport has been extensively studied over the past century in regard to its importance for Earth surface processes such as natural riverbed morph…
A minimal coupled fluid-discrete element model for bedload transport
Raphael Maurin, Julien Chauchat, Bruno Chareyre +1
A minimal Lagragian two-phase model to study turbulent bedload transport focusing on the granular phase is presented, and validated with experiments. The model intends to describe…
Dense granular flow rheology in turbulent bedload transport
Raphael Maurin, Julien Chauchat, Philippe Frey
The local granular rheology is investigated numerically in turbulent bedload transport. Considering spherical particles, steady uniform configurations are simulated using a coupled…
