A turbulent wall jet, jet Reynolds number of 30 7000, issuing from a rectangular nozzle adjacent to a plane surface is experimentally examined for different thicknesses of the nozzle upper boundary and for different heights of the external co-flow above the jet.
The object o f the study is to understand the role o f nozzle lip thickness and external stream height on the downstream development of the flow. Using cross hot-wire anemometry the velocity, shear stress and normal stress profiles of the flow were measured. The role of the external stream height is primarily to truncate the downstream distance for which a wall jet profile can be measured. No trend exists in the measurements due to increasing the lip thickness and it is postulated that the flow converts from a shear flow to a wake flow with increasing lip thickness.
