Abstract
The current study explored the flowfield characteristics of an induced recirculation zone resulting from a transverse slot jet issuing in a cross flow. The slot jet spanned 95% of the full channel spanwise dimension which resulted in a highly three-dimensional mean flowfield. Experimental investigations were carried out at various jet momentums for two different transverse slot jet thicknesses. Velocity field data were gathered using digital particle image velocimetry and hot-wire anemometry. The momentum ratio of the jet to the channel was found to be the leading parameter for scaling the dimensions of the mean recirculation zone. The jet thickness demonstrated an influence on the level of three-dimensionality, turbulence levels, and integral length scales.
