Flow characteristics of a two-dimensional air jet issuing from a nozzle of 5mm in width which is parallel to a horizontal wall with the vertical distance L have been experimentally and analytically investigated. The adjacent wall jet consists of three regions in the flow direction and the velocity profiles in each region are approximately composed of a free jet profile and a one-fifteenth power law profile. The flow characteristics are independent of Re (=u_o・L/ν=2.3×lO^4〜4.0×1O^4,u_o ; maximum of u at the upper end of the wall, ν ; the kinematic viscosity) and are of similarity. The bend of the main stream line, that is, the locus of the maximum velocities, was analyzed by using the momentum equations and the energy equations, The results agreed with the experimental results.
