Second sound resonators and tweezers as vorticity or velocity probes : fabrication, model and method
Eric Woillez, Jérôme Valentin, Philippe-E. Roche
An analytical model of open-cavity second sound resonators is presented and validated against simulations and experiments in superfluid helium using a new resonator design that ach…
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…
Local measurement of vortex statistics in quantum turbulence
Eric Woillez, Jérôme Valentin, Philippe-E Roche
The density fluctuations of quantum vortex lines are measured in a turbulent flow of superfluid He, at temperatures corresponding to superfluid fraction of 16%, 47% and 81%. The pr…
Cooling with a subsonic flow of quantum fluid
Pantxo Diribarne, Bernard Rousset, Yuri A. Sergeev +3
Miniature heaters are immersed in flows of quantum fluid and the efficiency of heat transfer is monitored versus velocity, superfluid fraction and time. The fluid is He helium…
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…
Detection of vortex coherent structures in superfluid turbulence
E Rusaouen, B Rousset, P. -E Roche
Filamentary regions of high vorticity irregularly form and disappear in the turbulent flows of classical fluids. We report an experimental comparative study of these so-called " co…
