An experimental study has been made of the reattachment of a radial turbulent jet flow discharged from a cylindrical nozzle on an adjacent offset disc plate. The effects of step height (distance of nozzle center plane from the offset plate), and control flow rate (ratio of control flow to main jet flow, suction and blowing)on flow pattern near the nozzle outlet section were investigated. Mean velocity and turbulent velocity distributions were measured with the aid of Hot-wire anemometer. The velocity profile, shape and length of a jet potential core, and a deflection of jet center axis depend on the combination of the step height and control flow rate. An oil film flow visualizing technique was also applied to determination of the flow pattern.
