Mixing and unmixing induced by active camphor particles
Clément Gouiller, Florence Raynal, Laurent Maquet +4
In this experimental study, we report on the mixing properties of interfacial colloidal floaters (glass bubbles) by chemical and hydrodynamical currents generated by self-propelled…
Kolmogorovian active turbulence of a sparse assembly of interacting swimmers
Mickael Bourgoin, Ronan Kervil, Cecile Cottin-Bizonne +3
Active matter, composed of self-propelled entities, forms a wide class of out-of-equilibrium systems that display striking collective behaviors among which the so-called active tur…
Advection and diffusion in a chemically induced compressible flow
Florence Raynal, Mickael Bourgoin, Cécile Cottin-Bizonne +2
We study analytically the joint dispersion of Gaussian patches of salt and colloids in linear flows, and how salt gradients accelerate or delay colloid spreading by diffusiophoreti…
Diffusiophoresis at the macroscale
Cyril Mauger, Romain Volk, Nathanael Machicoane +4
Diffusiophoresis, a ubiquitous phenomenon that induces particle transport whenever solute concentration gradients are present, was recently observed in the context of microsystems…
Experimental evidence of slippage breakdown for a superhydrophobic surface in a microfluidic device
Guido Bolognesi, Cecile Cottin-Bizonne, Christophe Pirat
A full characterization of the water flow past a silicon superhydrophobic surface with longitudinal micro-grooves enclosed in a microfluidic device is presented. Fluorescence micro…
Chaotic mixing in effective compressible flows
Romain Volk, Cyril Mauger, Mickael Bourgoin +3
We study numerically joint mixing of salt and colloids by a chaotic velocity field , and how salt inhomogeneities accelerate or delay colloid mixing by inducing a veloc…
