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…
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…
Markov property of Lagrangian turbulence
A. Fuchs, M. Obligado, M. Bourgoin +3
Based on direct numerical simulations with point-like inertial particles, with Stokes numbers, , , and , transported by homogeneous and isotropic turbulen…
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…
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}…
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…
Simultaneous 3D measurement of the translation and rotation of finite size particles and the flow field in a fully developed turbulent water flow
Simon Klein, Mathieu Gibert, Antoine Bérut +1
We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles toge…
Where do small, weakly inertial particles go in a turbulent flow?
Mathieu Gibert, Haitao Xu, Eberhard Bodenschatz
We report experimental results on the dynamics of heavy particles of the size of the Kolmogorov-scale in a fully developed turbulent flow. The mixed Eulerian structure function of…
Inertial effects on two-particle relative dispersion in turbulent flows
M. Gibert, H. Xu, E. Bodenschatz
We report experimental results on the relative motion of pairs of solid spheric particles with initial separations in the inertial range of fully developed turbulence in water. The…
Lagrangian temperature, velocity and local heat flux measurement in Rayleigh-Benard convection
Yoann Gasteuil, Woodrow Shew, Mathieu Gibert +3
We have developed a small, neutrally buoyant, wireless temperature sensor. Using a camera for optical tracking, we obtain simultaneous measurements of position and temperature of t…
An instrumented tracer for Lagrangian measurements in Rayleigh-Bénard convection
Woodrow L. Shew, Yoann Gasteuil, Mathieu Gibert +2
We have developed novel instrumentation for making Lagrangian measurements of temperature in diverse fluid flows. A small neutrally buoyant capsule is equipped with on-board electr…
