CHIMERA: A wide Reynolds number range Taylor-Couette facility
Pantxo Diribarne, Jérôme Chartier, Jérôme Duplat +1
We present a Taylor-Couette facility designed to investigate angular momentum transport over a wide range of Reynolds numbers, from moderate regimes in gases to extreme and potenti…
Kolmogorov Cascade as the Governing Mechanism for Intervortex Spacing in Quantum Turbulence
Clément Bret, Pantxo Diribarne, Jérôme Duplat +1
In this paper, we investigate inertially forced isothermal quantum turbulence (coflow of normal and superfluid components) at temperatures of 1.6 and 2 K. The experiments are carri…
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…
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…
Multi-scale energy budget of inertially driven turbulence in normal and superfluid helium
Fatimata Sy, Pantxo Diribarne, Bernard Rousset +2
In this paper we present a novel hydrodynamic experiment using liquid He. The flow is forced inertially by a canonical oscillating grid using either its normal (He~I) or superf…
Heat transfer enhancement on thin wires in superfluid helium forced flows
Davide Duri, Christophe Baudet, Jean-Paul Moro +2
In this paper, we report the first evidence of an enhancement of the heat transfer from a heated wire by an external turbulent flow of superfluid helium. We used a standard Pt-Rh h…
Probing quantum and classical turbulence analogy through global bifurcations in a von Kármán liquid Helium experiment
B Saint-Michel, E Herbert, J Salort +15
We report measurements of the dissipation in the Superfluid Helium high REynold number von Karman flow (SHREK) experiment for different forcing conditions, through a regime of glob…
Turbulent velocity spectra in superfluid flows
J. Salort, C. Baudet, B. Castaing +12
We present velocity spectra measured in three cryogenic liquid 4He steady flows: grid and wake flows in a pressurized wind tunnel capable of achieving mean velocities up to 5 m/s a…
Characterization of turbulence in inhomogeneous anisotropic flows
Pierre-Philippe Cortet, Pantxo Diribarne, Romain Monchaux +3
We introduce a global quantity that characterizes turbulent fluctuations in inhomogeneous anisotropic flows. This time-dependent quantity is based on spatial averages of global…
Fluctuation-Dissipation Relations and statistical temperatures in a turbulent von Kármán flow
Romain Monchaux, Pierre-Philippe Cortet, Pierre-Henri Chavanis +4
We experimentally characterize the fluctuations of the non-homogeneous non-isotropic turbulence in an axisymmetric von Kármán flow. We show that these fluctuations satisfy relation…
Vortex density spectrum of quantum turbulence
Philippe-Emmanuel P. -E. Roche, Pantxo Diribarne, Thomas Didelot +3
The fluctuations of the vortex density in a turbulent quantum fluid are deduced from local second-sound attenuation measurements. These measurements are performed with a micromachi…
