Helical Ribbons: Simple Chiral Sedimentation
Elias Huseby, Josephine Gissinger, Fabien Candelier +4
We investigate the sedimentation of chiral particles in viscous fluid flow. We identify helical ribbons as simple particles with strong translation-rotation coupling whose symmetry…
Spinning and tumbling of long fibers in isotropic turbulence
Theresa B. Oehmke, Ankur D. Bordoloi, Evan Variano +1
We simultaneously measure both spinning and tumbling components of rotation for long near-neutrally buoyant fibers in homogeneous and isotropic turbulence. The lengths and diameter…
Lagrangian time scale of rotation for inertial fibers in isotropic turbulence
Ankur D. Bordoloi, Gautier Verhille, Evan Variano
Using time-resolved measurements of the orientation of rigid inertial fibers in a turbulence-tank, we investigate the autocorrelation of their tumbling rate. The correlation time (…
Dynamo regimes and transitions in the VKS experiment
M. Berhanu, G. Verhille, J. Boisson +14
The Von K{á}rm{á}n Sodium experiment yields a variety of dynamo regimes, when asymmetry is imparted to the flow by rotating impellers at different speed F1 and F2. We show that as…
Long-term memory in experiments and numerical simulations of hydrodynamic and magnetohydrodynamic turbulence
Pablo Mininni, Pablo Dmitruk, Philippe Odier +5
We analyze time series stemming from experiments and direct numerical simulations of hydrodynamic and magnetohydrodynamic turbulence. Simulations are done in periodic boxes, but wi…
Induction in a von Karman flow driven by ferromagnetic impellers
Gautier Verhille, Nicolas Plihon, Mickael Bourgoin +2
We study magnetohydrodynamics in a von Kármán flow driven by the rotation of impellers made of material with varying electrical conductivity and magnetic permeability. Gallium is t…
