Probing dissipation in spreading drops with granular suspensions
Alice Pelosse, Élisabeth Guazzelli, Matthieu Roché
In this article, we study the spreading of droplets of density-matched granular suspensions on the surface of a solid. Bidispersity of the particle size distribution enriches the c…
Viscous-inertial transition in dense granular suspension
Franco Tapia, Mie Ichihara, Olivier Pouliquen +1
Granular suspensions present a transition from a Newtonian rheology in the Stokes limit to a Bagnoldian rheology when inertia is increased. A custom rheometer which can be run in a…
Spreading of granular suspensions on a solid surface
Menghua Zhao, Alice Pelosse, Mathieu Oléron +3
We examine the spreading of a suspension of non-Brownian spheres suspended in a Newtonian liquid on a solid substrate. We show that the spreading dynamics is well described by the…
The influence of surface roughness on the rheology of immersed and dry frictional spheres
Franco Tapia, Olivier Pouliquen, Elisabeth Guazzelli
Pressure-imposed rheometry is used to examine the influence of surface roughness on the rheology of immersed and dry frictional spheres in the dense regime. The quasi-static value…
Scale-free channeling patterns near the onset of erosion of sheared granular beds
Pascale Aussillous, Zhenhai Zou, Élisabeth Guazzelli +2
Erosion shapes our landscape and occurs when a sufficient shear stress is exerted by a fluid on a sedimented layer. What controls erosion at a microscopic level remains debated, es…
Falling Jets of Particles in Viscous Fluids
Florent Pignatel, Maxime Nicolas, Elisabeth Guazzelli +1
This fluid dynamics video presents experiments and simulations of gravity-driven particulate jets in viscous fluids at low Reynolds number. An initially straight jet is shown to de…
