E=mc and the negative pressure of Dark Energy
Bernard Castaing
According to recent observations, the Dark Energy would represent 70% of the content of our Universe. The most popular way to account for this Dark Energy make use of the Cosmologi…
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…
A phenomenological theory of Eulerian and Lagrangian velocity fluctuations in turbulent flows
Laurent Chevillard, Bernard Castaing, Alain Arneodo +3
A phenomenological theory of the fluctuations of velocity occurring in a fully developed homogeneous and isotropic turbulent flow is presented. The focus is made on the fluctuation…
Static spectroscopy of a dense superfluid
Sophie Villerot, Bernard Castaing, Laurent Chevillard
Dense Bose superfluids, as HeII, differ from dilute ones by the existence of a roton minimum in their excitation spectrum. It is known that this roton minimum is qualitatively resp…
Universal intermittent properties of particle trajectories in highly turbulent flows
ICTR, :, A. Arneodo +27
We present a collection of eight data sets, from state-of-the-art experiments and numerical simulations on turbulent velocity statistics along particle trajectories obtained in dif…
