On the investigation of properties of superfluid He turbulence using a hot-wire signal
P. Diribarne, M. Bon-Mardion, A. Girard +17
We report hot-wire measurements performed in two very different, co- and counter-rotating flows, in normal and superfluid helium at 1.6 K, 2 K, and 2.3 K. As recently reported, the…
Pair dispersion in inhomogeneous turbulent thermal convection
Olivier Liot, David-Martin-Calle, Amélie Gay +3
Due to large scale flow inhomogeneities and the effects of temperature, turbulence small-scale structure in thermal convection is still an active field of investigation, especially…
Structure, dynamics and reconnection of vortices in a nonlocal model of superfluids
Jason Reneuve, Julien Salort, Laurent Chevillard
We study the reconnection of vortices in a quantum fluid with a roton minimum, by numerically solving the Gross-Pitaevskii (GP) equations. A non-local interaction potential is intr…
Thermal boundary layers in turbulent Rayleigh-Bénard convection with rough surfaces
Ronald du Puits, Alice Loesch, Julien Salort +1
We present highly resolved measurements of the near-wall temperature field in thermally driven convection at a rough surface. Our measurements have been undertaken in a very large…
Intermittency of quantum turbulence with superfluid fractions from 0% to 96%
Eléonore Rusaouen, Benoît Chabaud, Julien Salort +1
The intermittency of turbulent superfluid helium is explored systematically in a steady wake flow from 1.28 K up to T>2.18K using a local anemometer. This temperature range spans r…
Velocity fluctuations and boundary layer structure in a rough Rayleigh-B{é}nard cell filled with water
Olivier Liot, Quentin Ehlinger, Elonore Rusaouën +3
We report Particle Image Velocimetry of the Large Scale Circulation and the viscous boundary layer in turbulent thermal convection. We use two parallelepipedic Rayleigh-B{é}nard ce…
