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…
Nonlinear behavior of a non-helical dynamo
P. D. Mininni, Y. Ponty, D. C. Montgomery +3
A three-dimensional numerical computation of magnetohydrodynamic dynamo behavior is described. The dynamo is mechanically forced with a driving term of the Taylor-Green type. The m…
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…
Reply to Comment on " Universal Fluctuations in Correlated Systems"
S. T. Bramwell, K. Christensen, J. -Y. Fortin +7
Reply to the comment, cond-mat/0209398 by by N.W. Watkins, S.C. Chapman, and G. Rowlands
The alpha effect and its saturation in a turbulent swirling flow generated in the VKS experiment
F. Petrelis, M. Bourgoin, L. Marie +6
We report the experimental observation of the alpha-effect. It consists in the generation of a current parallel to a magnetic field B0 applied to a turbulent swirling flow of liqui…
Intermittency and non-Gaussian fluctuations of the global energy transfer in fully developed turbulence
B. Portelli, P. C. W. Holdsworth, J. -F. Pinton
We address the experimentally observed non-Gaussian fluctuations for the energy injected into a closed turbulent flow at fixed Reynolds number. We propose that the power fluctuatio…
