Mean velocity and turbulence together with pressure distributions of jets issuing from ring nozzles with various openings, and spreading out radially over a flat smooth plate were studied. By changing the diameter and width of nozzles and discharge velocity, the flow pattern was measured. Flow field in the main region has been divided into two regions at the point of maximum flow velocity, that is, inner layer near the wall and outer layer away from the wall. Velocity profile in the inner layer is similar to Glauert's curve obtained for a radial wall jet, and the one in the outer layer agrees well with Goertler's curve for a two-dimensional free jet. Maximum flow velocity decays and growth of the jet half width lie on a single curve by making use of an equivalent nozzle width which contains the diameter and width of the nozzle.
