Plane Wake Near a Swept Wing
Experiments by Pailhas and Jayaraman
Description
Measurements were taken in the wake in the vicinity of a wing-body junction, with a symmetric airfoil at an angle of incidence of 15o, and sweep angle of 22o.
The Reynolds number based on chord was Rechord=500,000.
Measurement Techniques
Velocities were measured with X-hot-wire probes.
Available Measurements
Data available includes mean velocities and Reynolds stresses across x-z planes at a number of y locations.
Sample plots of selected quantities are available.
The data can be downloaded as compressed archives from the links below, or as individual files.
