CFD Comparisons with Updated NASA Juncture Flow Data

The purpose of the NASA Juncture Flow experiment is to acquire high-quality flowfield
details deep in the corner of a wing-body junction specifically for the purpose of CFD validation.
A second phase of testing was recently completed, which includes both laser doppler
velocimetry and particle image velocimetry measurements. This paper describes
the recent experiment and its results. It also makes detailed comparisons between
the experimental data and a new version of a widely-used CFD turbulence model for
Reynolds-averaged Navier-Stokes,
which was recently developed to improve separated corner flow predictions.
The CFD results generally produce very good qualitative agreement with the experiment, although
they are less accurate inside of the separation region, as expected.
