Effective description of Taylor dispersion in strongly corrugated channels
Arthur Alexandre, Thomas Guérin, David S. Dean
Taylor dispersion in periodic but highly corrugated channels is studied. Exact analytical expressions for the long-time diffusion constant and drift along the channel are derived t…
Self-phoretic oscillatory motion in a harmonic trap
A. Alexandre, L. Anderson, T. Collin-Dufresne +2
We consider the motion of a harmonically trapped overdamped particle, which is submitted to a self-phoretic force, that is proportional to the gradient of a diffusive field for whi…
Non-Gaussian diffusion near surfaces
Arthur Alexandre, Maxime Lavaud, Nicolas Fares +6
We study the diffusion of particles confined close to a single wall and in double-wall planar channel geometries where the local diffusivities depend on the distance to the boundar…
How stickiness can speed up diffusion in confined systems
Arthur Alexandre, Matthieu Mangeat, Thomas Guérin +1
The paradigmatic model for heterogeneous media used in diffusion studies is built from reflecting obstacles and surfaces. It is well known that the crowding effect produced by thes…
Generalized Taylor dispersion for translationally invariant microfluidic systems
Arthur Alexandre, Thomas Guérin, David S. Dean
We consider Taylor dispersion for tracer particles in micro-fluidic planar channels with strong confinement. In this context, the channel walls modify the local diffusivity tensor…
