%X <p>We
present an experimental benchmark database for the transitional cavity flow.
The database is obtained by planar Particle Image Velocimetry measurements at
the median plane of the cavity model, for Reynolds numbers between 6,300 and
19,000 based on the cavity height. A detailed uncertainty analysis
of the experimental results is performed via the correlation statistics method
for PIV uncertainty quantification and linear error propagation.</p><p><br></p><p>The data contain the following variables:</p><p>- x/H and y/H: locations (relative to the cavity H) in the streamwise and transverse directions, respectively</p><p>-u, v: streamwise and transverse velocity components, respectively. These quantities are normalized with respect to the free-stream velocity.</p><p>- TKE: turbulent kinetic energy. The TKE is normalized with respect to the square of the free-stream velocity.</p><p>- Rxy: shear Reynolds stress. Rxy is normalized with respect to the square of the free-stream velocity.</p><p>- Uncertainties of the above quantities (also normalized)</p><p>- isValid: parameter that assumes the value 1 for valid vectors and 0 for invalid vectors.</p>
