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…
Effects of electromagnetic waves on the electrical properties of contacts between grains
S. Dorbolo, A. Merlen, M. Creyssels +3
A DC electrical current is injected through a chain of metallic beads. The electrical resistances of each bead-bead contacts are measured. At low current, the distribution of these…
Heat Transfer in Turbulent Rayleigh-Benard Convection below the Ultimate Regime
P. -E. Roche, B. Castaing, B. Chabaud +1
A Rayleigh-Bénard cell has been designed to explore the Prandtl (Pr) dependence of turbulent convection in the cross-over range and for the full range of soft and hard…
Unified Multifractal Description of Velocity Increments Statistics in Turbulence: Intermittency and Skewness
L. Chevillard, B. Castaing, E. Leveque +1
The phenomenology of velocity statistics in turbulent flows, up to now, relates to different models dealing with either signed or unsigned longitudinal velocity increments, with ei…
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…
