Phoresis in cellular flows: from enhanced dispersion to blockage
Romain Volk, Michaël Bourgoin, Charles-Édouard Bréhier +1
In this article, we study numerically the dispersion of colloids in a two-dimensional cellular flow in the presence of an imposed mean salt gradient. Owing to the additional scalar…
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…
Diffusiophoresis, Batchelor scale and effective Péclet numbers
Florence Raynal, Romain Volk
We study the joint mixing of colloids and salt released together in a stagnation point or in a globally chaotic flow. In the presence of salt inhomogeneities, the mixing time is st…
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…
