Numerical investigation of mode failures in submerged granular columns
Eduard Puig Montellà, Julien Chauchat, Cyrille Bonamy +3
In submerged sandy slopes, soil is frequently eroded as a combination of two main mechanisms: breaching, which refers to the retrogressive failure of a steep slope forming a turbid…
A modified kinetic theory for frictional-collisional bedload transport valid from dense to dilute regime
Rémi Chassagne, Julien Chauchat, Cyrille Bonamy
Modelling sediment transport is still a challenging problem and is of major importance for the study of particulate geophysical flows. In this work, the modelling of sediment trans…
On the physical origin of enhanced turbulent-dispersion of inertial particles in boundary layer flows
Julien Chauchat, David Hurther, Thibaud Revil-Baudard +2
One of the most enigmatic science question concerning inertial particle transport by a turbulent boundary layer flow is the value of the turbulent Schmidt number as the ratio of pa…
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…
A finite-size correction model for two-fluid Large-Eddy Simulation of particle-laden boundary layer flow
Antoine Mathieu, Julien Chauchat, Cyrille Bonamy +2
In this paper the capabilities of the turbulence-resolving Eulerian-Eulerian two-phase flow model to predict the suspension of mono-dispersed finite-sized solid particles in a boun…
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…
