This paper presents the results of an experimental investigation of a turbulent cylindrical wall jet impinging normally on a flat plate. This type of jet flow may have properties including boundary layer separation and reattachment on the wall. Before dealing with this jet flow, this report describes the fundamental properties of three types of jet flow : a circular free jet from a circular nozzle, a cylindrical wall jet from an annular nozzle, and the impinging jet of a circular free jet with the flat plate normally. The changes of the maximum jet velocity, the jet half-width, the turbulence at the velocity maxima, and the static pressure for each jet flow are examined, and the results are compared with those obtained for the jet flow by the other investigators.
