Zero-Mean Oscillations Drive Recirculations in Potential Flows at Vanishing Reynolds Number
Alexandre S. Avaro, Leon V. Gebhard, Gabriel Amselem +1
Recirculating flows are central to transport phenomena, but their generation in potential flows requires additional physical mechanisms. We show experimentally that recirculation a…
Designing single-layer PDMS devices for micron to millimeter-scale deformations
Leon V. Gebhard, Alexandre S. Avaro, Gabriel Amselem +1
The elasticity of PDMS has played a central role in advancing important microfluidic technologies, ranging from early valves to sophisticated organ-on-a-chip systems. However, most…
Motion and hydrodynamic resistance of an elastic bead confined in a square microchannel
Charles Paul Moore, Hiba Belkadi, Brouna Safi +2
Cells and other soft particles are often forced to flow in confined geometries in both laboratory and natural environments, where the elastic deformation induces an additional drag…
Valveless pumping at low Reynolds numbers
Amselem Gabriel, Clanet Christophe, Benzaquen Michael
Pumping at low Reynolds number is a ubiquitously encountered feature, both in biological organisms and engineered devices. Generating net flow requires the presence of an asymmetry…
Monitoring the orientation of rare-earth-doped nanorods for flow shear tomography
Jongwook Kim, Sebastien Michelin, Michiel Gilberts +9
Rare-earth phosphors exhibit unique luminescence polarization features originating from the anisotropic symmetry of the emitter ion's chemical environment. However, to take advanta…
Breaking anchored droplets in a microfluidic Hele-Shaw cell
Gabriel Amselem, P. T. Brun, François Gallaire +1
We study microfluidic self digitization in Hele-Shaw cells using pancake droplets anchored to surface tension traps. We show that above a critical flow rate, large anchored droplet…
