This paper presents the results of an experimental study on the control of the deflection and reattachment of a radial wall jet through comparatively wide spaced two parallel disks, with an additional control flow. The flow field may be considered as having properties including those of the deflected jet, reattached jet and wall jet. The effects of opposite wall height (distance of opposite wall surface from the nozzle center plane) and control flow rate (ratio of control flow rate to main jet flow rate) on the flow pattern near the nozzle outlet section were investigated. The velocity profile, shape and length of a jet potential core, and the deflection of a jet center axis depend mainly on the combination of the opposite wall height and the control flow rate.
