An experimental study has been made on the control of the reattachment of a radial turbulent wall jet through comparatively wide spaced two parallel disks, with an additional control flow. Static pressure distributions along the side wall and the opposite wall, and also across the jet flow were measured with half disk type and a disk type pressure holes. 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 through tow parallel disks were investigated. The position of reattachment to the side wall surface, and pressure at this depend mainly on the combination of the opposite wall height and the control flow rate.
