Plane Wake Near a Swept Wing


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 \(Re_{chord} = 500,000\).

Velocities were measured with X-hot-wire probes.

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.
