The Coanda effect, or the phenomenon of a jet running along a curved wall is analysed with a two-dimensional approach assuming an ideal fluid. A thick jet emerging from a nozzle with an arbitrary kick down angle is mainly concerned, relative to the upper-surface-blowing high lift concept. The result of the free stream line analysis of a jet running along an infinite plane wall is conformally transformed under the constraint of the conservation of the free stream line condition, and the Coanda flow along the curved wall is deduced. Not only the shaped of the stream lines but also the flow velocity vector diagram and the wall pressure coefficient are calculated. The effect of the finiteness of a plane wall or the existence of the trailing edge of a wing/flap is also evaluated. Computation is executable with a 16-bit desk top computer, and programs written in the BASIC language are available.
