• The radial flow of a thin liquid film, formed by water discharge through a small cylindrical opening between a circular nozzle and a horizontal plate, is studied experimentally. The velocity profile in a thin liquid film was measured with the aid of Laser Doppler Velocimeter. The results show that a boundary layer gradually grows in the downstream direction and finally the whole flow merges into a boundary layer, and that the transition from laminar to turbulent flow occurs when the discharge Reynolds number is large. The experimental results about the process of the flow development were compared with the theoretical values calculated by means of boundary layer theory.
