Wind Tunnel Experiment Data Files

The following files were obtained by student groups from wind tunnel tests carried out in the Department's wind tunnels. All files are in "raw data" format, directly as recorded from the tunnel system. There are no guarantees that any of this data has been correctly recorded and does not contain any obvious errors in data input. No corrections for wind tunnel effects have been applied to the data. Check the header information in each file to accurately determine the experiment to which it applies. 

2-D Aerofoil Section Data

Measured from the tunnel force balance system.

• NACA 0012 Aerofoil Section test
• NACA 0012 Aerofoil with 60 Deg Split Flap

2-D Section 0012 Boundary Layer and Wake traverse data.

The following data files were obtained using pitot-static probe measurements in a traverse of the boundary layer and downstream wake of the 0012 aerofoil section. Note that position (vertical and horizontal) data and flow velocity data are uncalibrated. You must get the appropriate calibration data files to use the data correctly. All boundary layer traverses were done for an angle of attack of zero degs.

• Wake Traverse (Alpha 0 Deg)
• Wake Traverse (Alpha 1 Deg)
• Wake Traverse (Alpha 2 Deg)
• Wake Traverse (Alpha -1 Deg)
• Wake Traverse (Alpha -2 Deg)
• Wake Traverse (Alpha -3 Deg)
• Wake Traverse (Traverse Position Calibration)

Flat Plate Boundary Layer data.

The following data files were obtained using a pitot probe measurement, traversing from the surface of the plate out into the uniform stream. Two classes of boundary layer have been measured. Calibration information for the probe position is found here: Probe Calibration
