The flow characteristics of a three-dimensiomal air jet issuing from nozzle 20-60 mm in diameter, which is parallel to a horizontal wall with the vertical distance, have been experimentally investigated. The contours of the jet boundary at a section perpendicular to the axis are approximately expressed by two different circular arcs, and in order to express the variation of the contour along the axis, an empirical expression for the locus of the points of the axial maximum velocities and expressions for two typical radial radii from the points are determined, respectively. The distributions of decay of the maximum velocity profiles along the radial radii and the distribution of shearing stress at the wall are clarified. The bend of the main streamline which is a feature of the present jet, the locus of the maximum velocities, is clarified.
