Friction Induces Anisotropic Propulsion in Sliding Magnetic Microtriangles
In viscous fluids, motile microentities such as bacteria or artificial swimmers often display different transport modes than macroscopic ones. A current challenge in the field aims at using friction asymmetry to steer the motion of microscopic particles. H ...
AMER CHEMICAL SOC2022Quantifying the transition of impact mechanisms of geophysical flows against flexible barrier
Flexible barriers have been increasingly used worldwide for mitigating natural hazards involving various geophysical flows. The analysis and design of flexible barriers need to distinguish two major impact mechanisms, runup and pile-up, which remain poorly ...
ELSEVIER2021A plane‐strain hydraulic fracture driven by a shear‐thinning Carreau fluid
Brice Tanguy Alphonse Lecampion, Lucas Pereira
We study the propagation of a plane‐strain hydraulic fracture driven by a shear thinning fluid following a Carreau rheology. We restrict to the impermeable medium case and quantify in details the impact on fracture growth of the shear‐thinning properties o ...
2021Effect of Fluid Viscosity on Earthquake Nucleation
Marie Estelle Solange Violay, Chiara Cornelio
Injection of fluids in geo-reservoirs can reduce the effective stresses at depth, lubricating the nearby faults, promoting slip and, potentially, earthquakes. High-viscous fluids are often used during hydraulic fracturing and production phases in geo-reser ...
2020Dynamic response of a compressible binary fluid mixture
Binary fluids are present in a wide variety of systems at microscales, such as microfluidic devices containing drops, fluids with air bubbles trapped in them, and devices designed to mix fluids or to make two fluid substances react. Microfluidics devices a ...
2020Propagation of fluid driven fractures in transversely isotropic material
The propagation of fluid driven fractures is used in a number of industrial applications (well stimulation of unconventional reservoirs, development of deep geothermal systems) but also occurs naturally (magmatic dyke intrusion). While the mechanics of hyd ...
EPFL2020Assembling Ni-Fe Layered Double Hydroxide 2D Thin Films for Oxygen Evolution Electrodes
Hubert Girault, Andreas Stephan Lesch, Victor Costa Bassetto, Massimo Rosa
Continuous hydrothermal flow synthesis (CHFS) of Ni-Fe layered double hydroxide (LDH) leads to waterborne dispersions of 2D nanoplatelets in the range of 10-50 nm in lateral size. Conversion of the as-synthesized LDH nanoplatelet dispersion into inkjet pri ...
AMER CHEMICAL SOC2020Interaction and breakup of droplet pairs in a microchannel Y-junction
We combine theory, numerical simulation, and experiments to investigate the breakup of two identical droplets entering a Y-junction with controlled spatial offset by which the second droplet trails the first. Based on fully resolved 3D simulations, we desc ...
AMER PHYSICAL SOC2020Collective behavior of red blood cells in confined channels
We study the flow properties of red blood cells in confined channels, when the channel width is comparable to the cell size. We focus on the case of intermediate concentrations when hydrodynamic interactions between cells play a dominant role. This regime ...
2019Production of monodisperse drops from viscous fluids
Esther Amstad, Mathias Steinacher, Tomasz Radoslaw Szymborski, Armend Gazmeno Hati
Drops are often used as picoliter-sized reaction vessels, for example for high-throughput screening assays, or as templates to produce particles of controlled sizes and compositions. Many of these applications require close control over the size of drops, ...
