==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}
