Abstract

An experimental study has been presented which deals with the 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 controled flow from an annular nozzle, Static pressure distributions along the side wall and across the jet flow were measured using a disk-type pressure hole. The relation between the deflection of the main jet, the reattachment point on the side wall, the mean negative pressure in a recirculating flow region and the curvature of the jet center axis were obtained for various values of the control flow rate and the step height, which describe the length of and the pressure within the recirculating flow region.
