An experimental study has been made on deflection and reattachment of a radial turbulent jet (main jet) discharged from a cylindrical nozzle onto an adjacent disk plate in the presence of a lateral control flow from an annular nozzle. Three parameters : the nozzle width of the control flow, the control flow rate and the nozzle distance between two nozzles, which describe the control flow, can be combined in one parameter, namely a control momentum flux. The relations between the deflection angle of the main jet, the reattachment position on the side wall and the control momentum flux for each step height were obtained. Also, the deflected and reattached jet flow properties for various experimental conditions were investigated.
