Mixing and sharpening at the interface of a two-layer fluid forced by random jets
Noé Clavier, Hugo Pradel, Romain Volk +2
Understanding mixing at density interfaces is essential for predicting transport in stratified environmental flows. Laboratory studies have mostly relied on steady, spatially unifo…
On the clustering of finite-size particles in turbulence
Lionel Fiabane, Robert Zimmermann, Romain Volk +2
We investigate experimentally the spatial distributions of heavy and neutrally buoyant particles of finite size in a fully turbulent flow. As their Stokes number (i.e. ratio of the…
Do finite size neutrally buoyant particles cluster?
Lionel Fiabane, Romain Volk, Jean-Francois Pinton +3
We investigate the preferential concentration of particles which are neutrally buoyant but with a diameter significantly larger than the dissipation scale of the carrier flow. Such…
Acceleration of heavy and light particles in turbulence: comparison between experiments and direct numerical simulations
R. Volk, E. Calzavarini, G. Verhille +4
We compare experimental data and numerical simulations for the dynamics of inertial particles with finite density in turbulence. In the experiment, bubbles and solid particles are…
Measurement of particle and bubble accelerations in turbulence
Romain Volk, Nicolas Mordant, Gautier Verhille +1
We use an extended laser Doppler technique to track optically the velocity of individual particles in a high Reynolds number turbulent flow. The particle sizes are of the order of…
Transport of magnetic field by a turbulent flow of liquid sodium
R. Volk, F. Ravelet, R. Monchaux +8
We study the effect of a turbulent flow of liquid sodium generated in the von Kármán geometry, on the localized field of a magnet placed close to the frontier of the flow. We obser…
