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…

Lagrangian diffusion properties of a free shear turbulent jet
Bianca Viggiano, Thomas Basset, Stephen Solovitz +7
A Lagrangian experimental study of an axisymmetric turbulent water jet is performed to investigate the highly anisotropic and inhomogeneous flow field. The measurements were conduc…

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…
