The experiment is performed in a wind tunnel with a 2m long working section and a 2.8 m¡Á0.2m cross-section. The boundary layer was tripped at the leading edge by two sets of tripping devices consisting of a 1mm diameter rod followed by a 5cm long strip of #40 grit sandpaper. The free-stream turbulence was less than 0.4%. 

The STREAMLINE software supplied by DANTEC was used for data acquisition and storage. A constant temperature anemometer was used to acquire the stream-wise velocity.

Two group of tests are carried out. One is named  BASE test, which means that the flow was without external forcing. Mearsurements were performed along the centerline of the airfoil at different stations: x/c=0.3, x/c=0.4, x/c=0.5 and x/c=0.6.  The other is named MB test, which was forced by a Pulse-Micro-Blowing injection located at x/c=0.3 and velocity was mearsured at  x/c=0.4.

The upstream velocity was 13.3m/s for BASE tests, which was measured by 1D single boundary layer probe and  2D 55p61 probe, respectively. The upstream velocity was 11.0m/s for the MB tests, which was measured by 2D 55p61 probe.
