A blind test on wind turbine wake modelling based on wind tunnel experiments: Phase I – The benchmark case

This data set ("Data files.zip") contains the wind tunnel measurement data from Phase I of the Blind test on wind turbine wake modelling based on wind tunnel experiments organised during the TWEET-IE project (www.tweet-ie.eu). This updated version replaces the older versions 1.0.0 (https://doi.org/10.5281/zenodo.10566401) and 1.1.0 (https://doi.org/10.5281/zenodo.11370112). All tests were conducted in the closed-loop, low-speed boundary layer wind tunnel of the Chair of Aerodynamics and Fluid Mechanics at Technische Universität München (TUM). The experiments concerned two wind turbines, aligned with the flow, one downstream of the other, at a distance of 5 diameters. For Phase I, no control was applied to the wind turbine models, which were operating at constant RPM. The turbine models, designed and manufactured by TUM, were instrumented with multiple sensors and actuators and had a diameter of 1.1M. Measurements include velocity, power and loads on the turbines. A detailed description of the experimental set up can be found in the accompanying document ("Data documentation.pdf"). File "Submission procedure.zip" includes the format description and the templates of the output data that should be submitted by the participants in the blind test comparison.
