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…
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…
