Studies on re-attaching wall jets
Abstract
The results of experimental investigations carried out on wall jets reattaching to an offset parallel plane surface are presented and compared with the results for plane wall jets. Experiments were carried out on a 1/4 inch nozzle at eight different offset ratios using three different jet inlet velocities. Measurements were made for re-attachment point, vortex center, jet velocity profile beyond the re-attachment point, the static pressure on the bottom wall and of shear stress. In the outer layer beyond the re-attachment point the flow behaved like a plane wall jet. The decay of maximal velocity and growth remained similar to that of a plane wall jet. Only the log law, representing the velocity distribution in the inner layer, differed from that of a plane wall jet.
