Stereo PIV:

This wing wake measurement with stereo PIV (2D3C) corresponds to an angle of attack of $\alpha$=0°.

• Info for Epsilon PIV:
The entire wake was measured with 3 lateral PIV regions placed at 0.5 chords downstream of the wing. The following orientation and coordinates must be used in the transformation tool of Epsilon PIV to positionate each PIV region correctly:

Orientation [°] = [ 90, 0, 90]

• Info for Epsilon Aero Data:
V0 = 20 m/s
Ps0 = 101325 Pa
Ts0 = 288 K
Sw = 0.2025 m^2

Five-hole probe calibration:

Three calibration charts are provided, which corresponds to the five-hole probe (5HP) used for the wake survey. The calibration charts were obtained at M=0.1, M=0.3 and M=0.5, although only M=0.1 must be used to process the wake survey data.

5HP wake survey:

This wing wake measurement with five-hole probe corresponds to an angle of attack of $\alpha$=10°. The entire wake was measured in two separated runs, one covering the main wake region, and a complementary run to survey the junction flow region.
