Abstract : A high velocity air jet (primary) was directed into a constant diameter duct where it mixed with a lower velocity concentric air stream (secondary). Experimental measurements of the static pressure distribution, mean velocity profiles and turbulence quantities were taken from the initial location where there was a step change in the primary and secondary velocity profiles to the downstream location where the flow was fully developed. Calculations of the momentum flux and wall shear stress were made using the mean velocity and pressure measurements. (Author)
