======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 15<sup>o</sup>, and sweep angle of 22<sup>o</sup>.  

The Reynolds number based on chord was \(Re_{chord} = 500,000\).

====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.

[[case040-plots|Sample plots]] of selected quantities are available.

The data can be downloaded as compressed archives from the links below, or as individual files.
