N2 - Seven profiles of streamwise velocity and velocity fluctuations were measured in the incoming boundary layer and immediately upstream of a 24-degree compression corner in a M∞ = 2.8, ReΘ = 1750 shock-wave/turbulent boundary-layer interaction. The measurements were made with Krypton Tagging Velocimetry (KTV) in 99% N2/1% Kr flow. Glob- ally seeding 1% Kr into the flow (premixed N2/Kr K-bottles from distributor) alters the major non-dimensional transport properties by 0.1-0.3%. The mean-velocity and velocity- fluctuation profiles in the incoming supersonic turbulent boundary layer were found to agree with datasets in the literature, thus, the baseline flow was established. The mean- velocity profiles in the region immediately upstream of the 24-degree compression corner were found to agree with Direct Numerical Simulation (DNS) results available in the literature. In addition, the presence of a shear layer was detected, and its location and orientation are compared to that in the literature.
