Description of Experiment
The experiment of TU München is described in detail by Furman and Breitsamter (2009). It has been performed in a low-speed wind tunnel of closed-return type with an open test section. The following measurement techniques have been used for the considered conditions: \begin{itemize} \item Steady surface pressure taps (sampling rate of 100 Hz, averaging time of 10 s). \item Unsteady surface pressure sensors (sampling rate of 2000 Hz, sample time of 40 s). \item Stereo Particle Image Velocimetry (Stereo-PIV) to measure time-averaged velocities. \item Hot-Wire Anemometry (HWA) to measure velocity fluctuations. \item Oil-flow visualization of the surface streamlines. \end{itemize}
