Dispersion versus diffusion in mixing fronts
Gauthier Rousseau, Satoshi Izumoto, Tanguy Le Borgne +1
Mixing fronts form when fluids with different chemical compositions are brought into contact. They influence a large range of biogeochemical processes in hydrological systems. An i…

Impact of pore-scale chaotic mixing on Darcy-scale reaction rates
Satoshi Izumoto, Gauthier Rousseau, Tanguy Le Borgne +1
Prediction of reactive transport in porous media remains challenging when pore scale incomplete mixing is at play. Previous experimental studies investigated chemical reactions in…

Revisiting the role of friction coefficients in granular collapses: confrontation of 3-D non-smooth simulations with experiments
Gauthier Rousseau, Thibaut Métivet, Hugo Rousseau +2
In this paper, transient granular flows are examined both numerically and experimentally. Simulations are performed using the continuous 3D granular model introduced in Daviet & Be…
