This paper presents the results of an experimental study on the control of the reattachment of a radial turbulent jet flow (main jet flow) discharged from a cylindrical nozzle onto an adjacent offset disc plate, with the addition of another control flow. distributions of mean velocity, turbulent velocity and wall static pressure were measured. The effects of step height and control flow rate (suction and blowing) on the flow properties at and after the reattachment point, i.e., deflection of jet center axis, reattachment point, changes of jet center velocity, turbulence at velocity maxima and jet half width were investigated. Velocity and turbulence profiles were compared with those of a two-dimensional wall jet flow and radial wall jet flow.
