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…
Pair Dispersion in Turbulence
Mickael Bourgoin, Nicholas T. Ouellette, Haitao Xu +2
Turbulent mixing of liquids and gasses is ubiquitous in nature. It is the basis of all industrial fluid mixing processes, and it determines the spread of pollutants or bioagents in…
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…
Roughness of stylolites: a stress-induced instability with non local interactions
J. Schmittbuhl, F. Renard, J. P. Gratier
We study the roughness of stylolite surfaces (i.e. natural pressure-dissolution surfaces in sedimentary rocks) from profiler measurements at laboratory scales. The roughness is sho…
