Description

The subject of this paper is the experimental determination of the flow characteristics of three-dimensional wall jets. The jets were produced from a diffuser with a rectangular outlet. The diffuser outlet size and flow rate were varied to produce both low and high outlet aspect ratios and Reynolds numbers. Velocity profile measurements were made to determine the centerline velocity decay and the extent of the lateral and vertical spread of the jet. Using a simple jet model, the velocity decay coefficients, virtual origins, and spread angles were deduced and compared with previously published results for smaller laboratory-scale jets.
