Intermittency of velocity time increments in turbulence
L. Chevillard, S. G. Roux, E. Leveque +3
We analyze the statistics of turbulent velocity fluctuations in the time domain. Three cases are computed numerically and compared: (i) the time traces of Lagrangian fluid particle…
Statistics of Fourier Modes of Velocity and Vorticity in Turbulent Flows : Intermittency and Long-Range Correlations
L. Chevillard, N. Mazellier, C. Poulain +2
We perform a statistical analysis of experimental fully developed turbulence longitudinal velocity data in the Fourier space. We address the controversial issue of statistical inte…
On the Rapid Increase of Intermittency in the Near-Dissipation Range of Fully Developed Turbulence
Laurent Chevillard, Bernard Castaing, Emmanuel Leveque
Intermittency, measured as log(F(r)/3), where F(r) is the flatness of velocity increments at scale r, is found to rapidly increase as viscous effects intensify, and eventually satu…
Lagrangian Velocity Statistics in Turbulent Flows: Effects of Dissipation
L. Chevillard, S. G. Roux, E. Leveque +3
We use the multifractal formalism to describe the effects of dissipation on Lagrangian velocity statistics in turbulent flows. We analyze high Reynolds number experiments and direc…
