Visualization of Inertial and Kelvin Waves on the Quantum Vortex Lattice in Superfluid Helium
Florian Lorin, Charles Peretti, Corentin Bourjaillat +3
Superfluid He subjected to steady rotation develops a regular lattice of quantum vortices aligned with the rotation axis. We prepare this lattice in a rotating cryostat, pertur…
The Cryogenic Lagrangian Exploration Module: a rotating cryostat for the study of quantum vortices in Helium II via particle seeding
Jeremy Vessaire, Charles Peretti, Florian Lorin +5
The study of quantum vortex dynamics in HeII offers great potential for advancing quantum-fluid models. Bose-Einstein condensates, neutron stars, and even superconductors exhibit q…
Direct visualization of the quantum vortex density law in rotating 4He
Mathieu Gibert, Charles Peretti, Jeremy Vessaire +1
The study of quantum vortex dynamics in He II holds great promise to refine quantum-fluid models. Bose-Einstein condensates, neutron stars or even superconductors exhibit quantum v…
Entrainment, diffusion and effective compressibility in a self-similar turbulent jet
Thomas Basset, Bianca Viggiano, Thomas Barois +5
An experimental Lagrangian study based on particle tracking velocimetry has been completed in an incompressible turbulent round water jet freely spreading into water. The jet is se…
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…

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…
Niobium nitride thin films for very low temperature resistive thermometry
Tuyen Nguyen, Adib Tavakoli, Sebastien Triqueneaux +10
We investigate thin film resistive thermometry based on metal-to-insulator-transition (niobium nitride) materials down to very low temperature. The variation of the NbN thermometer…
Turbulence attenuation by large neutrally buoyant particles
Mamadou Cisse, Ewe Wei Saw, Mathieu Gibert +2
Turbulence modulation by inertial-range-size, neutrally-buoyant particles is investigated experimentally in a von Kármán flow. Increasing the particle volume fraction $Φ_\mathrm{v}…
