Description/Abstract
Turbulence measurements were performed of an inclined jet in an otherwise flat plate turbulent boundary layer. The jet was produced using a rectangular nozzle. The pitch angle of the nozzle was 30o and the skew angle varied between 0o and 135o. The speed of the jet was the same as that of the oncoming freestream. Measurements revealed modifications to both turbulent kinetic energy (TKE) and stress distributions around the centre of the vortex and in the near-wall region. The influence of the wake of the jet featured prominently in the TKE distribution. The primary shear stress was found to be characterized by two areas of opposite signs and separated by the centre of the vortex at a skew angle higher than 30o. When the skew angle was varied, only qualitative changes were observed between 45o and 90o skew. Between 30o and 135o skew, an area of negative primary shear stress was observed between the centre of the vortex and the wall.
