Extract

The phenomenon of a jet emerging tangentially to a wall and flowing along the surface of the wall has long been known as a wall jet. Plane and curved wall jets have been investigated by many researchers in the past. In spite of many investigations in this field, a reasonably complete understanding of the curvature effects on the turbulent wall jet has not been achieved. This investigation, therefore, was intended to serve as a complementary study of curvature effects. Experiments were performed with a two-dimensional turbulent jet flow over a plane surface and over circular convex and concave surfaces of various radii in still air. The study was limited to the mean properties of the flow and was not concerned with the momentum loss on the surface.
