Superstatistical wind fields from point-wise atmospheric turbulence measurements
Jan Friedrich, Daniela Moreno, Michael Sinhuber +2
Accurate models of turbulent wind fields have become increasingly important in the atmospheric sciences, e.g., for the determination of spatiotemporal correlations in wind parks, t…
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…
Towards a Simplified Dynamic Wake Model using POD Analysis
David Bastine, Björn Witha, Matthias Wächter +1
We apply the proper orthogonal decomposition (POD) to large eddy simulation data of a wind turbine wake in a turbulent atmospheric boundary layer. The turbine is modeled as an actu…
Wind Energy and the Turbulent Nature of the Atmospheric Boundary Layer
Matthias Wächter, Hendrik Heißelmann, Michael Hölling +6
Wind turbines operate in the atmospheric boundary layer, where they are exposed to the turbulent atmospheric flows. As the response time of wind turbine is typically in the range o…
