Abstract
A flat plate wing was applied to a flow management of stronger wall jet with constant velocity ratio of Um/Ue=4 in a self-preserving development. Reynolds number based on jet height and jet flow velocity was kept to be constant of 12,000. The normal straight flat plate and three-dimensional wing were employed and located at the centre of the outer layer in the jet with constant angle of attach of -4 degree. The three-dimensional wing has notched trailing edge which is of the same order of half width of the jet, 2b2. The fluctuating velocity measurement and momentum flux evaluation were made with constant temperature anemometers. The two wings increase the maximum velocity and also velocity in the outer layer. Streamwise momentum flux integrated in the shear layer is increased by the wing manipulation. The three-dimensional wing gives larger increasing rate of the momentum flux. Longitudinal vortical structures are produced behind the threedimensional wing.
