A universal relation between intermittency and dissipation within and beyond homogeneous isotropic turbulence
F. Schmitt, A. Fuchs, J. Peinke +1
Fundamental quantities of turbulent flows, such as the dissipation \Vsix{parameter} and the intermittency \Vsix{parameter} , are examined in relation to each oth…
Experimental and Computational Investigation of a Fractal Grid Wake
André Fuchs, Wided Medjroubi, Hannes Hochstein +2
Fractal grids generate turbulence by exciting many length scales of different sizes simultaneously rather than using the nonlinear cascade mechanism to obtain multi-scale structure…
An open source MATLAB package to perform basic and advanced statistical analysis of turbulence data and other complex systems
André Fuchs, Swapnil Kharche, Matthias Wächter +1
We present a user-friendly open-source MATLAB\textsuperscript{\textregistered} package developed by the research group Turbulence, Wind energy and Stochastics (TWiSt) at the Carl v…
Instantons and the path to intermittency in turbulent flows
André Fuchs, Corentin Herbert, Joran Rolland +3
Processes leading to anomalous fluctuations in turbulent flows, referred to as intermittency, are still challenging. We consider cascade trajectories through scales as realizations…
Hybrid time series from PIV for characterization of turbulent flow fields: ASTRA -- Approach using Spatially and Temporally Resolved Advection
Tom T. B. Wester, André Fuchs, Joachim Peinke +1
Particle Image Velocimetry (PIV) has become increasingly popular to study structures in turbulent flows. PIV allows direct extraction and investigation of spatial structures in the…
Markov property of Lagrangian turbulence
A. Fuchs, M. Obligado, M. Bourgoin +3
Based on direct numerical simulations with point-like inertial particles, with Stokes numbers, , , and , transported by homogeneous and isotropic turbulen…
On universal features of the turbulent cascade in terms of non-equilibrium thermodynamics
Nico Reinke, Andre Fuchs, Daniel Nickelsen +1
Features of the turbulent cascade are investigated for various datasets from three different turbulent flows. The analysis is focused on the question as to whether developed turbul…
The Langevin Approach: a simple stochastic method for complex phenomena
Nico Reinke, André Fuchs, Wided Medjroubi +3
We describe a simple stochastic method, so-called Langevin approach, which enables one to extract evolution equations of stochastic variables from a set of measurements. Our method…
