Nonlocal Effects Reflect the Jamming Criticality in Frictionless Granular Flows Down Inclines
Matthieu Wyart, Hugo Robin Louis Perrin
The jamming transition is accompanied by a rich phenomenology such as hysteresis or nonlocal effects that is still not well understood. Here, we experimentally investigate a model frictionless granular layer flowing down an inclined plane as a way to disen ...
AMER PHYSICAL SOC2021Invariant solutions underlying small- and large-scale structures in turbulent boundary layers
Flows of gases and liquids interacting with solid objects are often turbulent within a thin boundary layer. As energy dissipation and momentum transfer are dominated by the boundary layer dynamics, many engineering applications can benefit from an improved ...
EPFL2020Modelling the vertical structure of turbulent free-surface flows over rough permeable beds
Christophe Ancey, Joris Heyman, Gauthier Paul Daniel Marie Rousseau
Understanding diffusive processes across the sediment-water interface is important for quantifying hyporheic exchanges and related biogeochemical processes (e.g., denitrification, biomass growth). Viscous, turbulent and dispersive effects all contribute to ...
2020Self-similar invariant solution in the near-wall region of a turbulent boundary layer at asymptotically high Reynolds numbers
Tobias Schneider, Sajjad Azimi
At sufficiently high Reynolds numbers, shear-flow turbulence close to a wall acquires universal properties. When length and velocity are rescaled by appropriate characteristic scales of the turbulent flow and thereby measured in inner units, the statistica ...
CAMBRIDGE UNIV PRESS2020Scanning PIV of turbulent flows over and through rough porous beds using refractive index matching
Christophe Ancey, Gauthier Paul Daniel Marie Rousseau
This paper presents image velocimetry measurements on turbulent flows adjacent to a permeable bed made of randomly packed glass particles. For measuring flow velocities inside the bed, the refractive index of the glass particles was matched with that of th ...
SPRINGER2020Intercomparison of Large-Eddy Simulations of the Antarctic Boundary Layer for Very Stable Stratification
Etienne Gabriel Henri Vignon, Jing Huang
In polar regions, where the boundary layer is often stably stratified, atmospheric models produce large biases depending on the boundary-layer parametrizations and the parametrization of the exchange of energy at the surface. This model intercomparison foc ...
SPRINGER2020Stationary Structures near the Kolmogorov and Poiseuille Flows in the 2d Euler Equations
We study the behavior of solutions to the incompressible 2d Euler equations near two canonical shear flows with critical points, the Kolmogorov and Poiseuille flows, with consequences for the associated Navier-Stokes problems. We exhibit a large family of ...
2020Turbulent Flows over Rough Permeable Beds in Mountain Rivers: Experimental Insights and Modeling
Gauthier Paul Daniel Marie Rousseau
Steep mountain streams exhibit shallow waters with roughness elements such as stones and pebbles that are comparable in size to flow depth. Owing to the difficulty in measuring fluid velocities at the interface, i.e., from the rough permeable bed to the fr ...
EPFL2019Slickwater hydraulic fracture propagation: near-tip and radial geometry solutions
Brice Tanguy Alphonse Lecampion, Haseeb Zia
We quantify the importance of turbulent flow on the propagation of hydraulic fractures (HF) accounting for the addition of friction reducing agents to the fracturing fluid (slickwater fluid). The addition in small quantities of a high molecular weight poly ...
2019Roll-up region of tip vortex: numerical investigation
Mohamed Farhat, Azin Amini, Matthieu Dreyer, Martino Reclari
The appearance of gas-filled vortices at the tip of hydraulic machines blades is usually associated with increase of losses, vibrations, noise and erosion risk. The understanding of the roll-up region, where the boundary layer on the pressure side crosses ...
