RADIAL FLOW OF A THIN LIQUID FILM (2ND REPORT, LIQUID FILM THICKNESS).

Abstract

The radial flow of a thin liquid film is studied experimentally. The experimental results about laminar flow are compared both with the theory of Watson and with the approximate solution for a film flow formed by a water jet falling vertically onto a horizontal plane, by using an equivalent length of opening instead of a radius of water jet. About the liquid film in which the transition from laminar to turbulent flow occurs, the approximate solution for turbulent region is compared with experimental results.
