Structure functions and flatness of streamwise velocity in a turbulent channel flow
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas B. Garnier
In this article, we present a multiscale characterization of the streamwise velocity of a turbulent channel flow. We study the 2nd and 4th order structure functions and the flatnes…
Relationship between unpredictability and intermittency in shell models of turbulence and experiments
Ewen Frogé, Carlos Granero-Belinchon, Stéphane G. Roux +2
We study the predictability of turbulent velocity signals using probabilistic analog-forecasting. Here, predictability is defined by the accuracy of forecasts and the associated un…
Analog-Based Forecasting of Turbulent Velocity: Relationship between Unpredictability and Intermittency
Ewen Frogé, Carlos Granero-Belinchon, Stéphane G. Roux +2
This study evaluates the performance of analog-based methodologies to predict, in a statistical way, the longitudinal velocity in a turbulent flow. The data used comes from hot wir…
Multiscale and Anisotropic Characterization of Images Based on Complexity: an Application to Turbulence
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas B. Garnier
This article presents a multiscale, non-linear and directional statistical characterization of images based on the estimation of the skewness, flatness, entropy and distance from G…
Revealing intermittency in experimental data with steep power spectra
Eric Falcon, S. G. Roux, Benjamin Audit
The statistics of signal increments are commonly used in order to test for possible intermittent properties in experimental or synthetic data. However, for signals with steep power…
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…
