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…

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…

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…
