Internal wave crystals
Sasan J. Ghaemsaidi, Michel Fruchart, Severine Atis
Geophysical fluids such as the ocean and atmosphere can be stratified: their density depends on the depth. As a consequence, they can host internal gravity waves that propagate in…
Anisotropic Particles Focusing Effect in Complex Flows
Severine Atis, Matthieu Leclair, Themistoklis Sapsis +1
Finite size effects can lead neutrally buoyant particles to exhibit different dynamics than tracer particles, and can alter their transport properties in fluid flows. Here we inves…
Using braids to quantify interface growth and coherence in a rotor-oscillator flow
Margaux Filippi, Marko Budisic, Michael R. Allshouse +3
The growth rate of material interfaces is an important proxy for mixing and reaction rates in fluid dynamics, and can also be used to identify regions of coherence. Estimating such…
Microbial range expansions on liquid substrates
Severine Atis, Bryan T. Weinstein, Andrew W. Murray +1
Despite the importance that fluid flow plays in transporting and organizing populations, few laboratory systems exist to systematically investigate the impact of advection on their…
Experimental evidence for three universality classes for reaction fronts in disordered flows
Séverine Atis, Awadhesh Kumar Dubey, Dominique Salin +3
Self-sustained reaction fronts in a disordered medium subject to an external flow display self-affine roughening, pinning and depinning transitions. We measure spatial and temporal…
Self-Sustained Reaction Fronts in Porous Media
Severine Atis, Sandeep Saha, Harold Auradou +2
We analyze experimentally chemical waves propagation in the disordered flow field of a porous medium. The reaction fronts travel at a constant velocity which drastically depends on…
