A theoretical model of a gas stream flowing co‐currently with a liquid film is established. The model is used to analyse the experimental results obtained for the co‐current flow of an air stream and a thin water film in a vertical rectangular duct. The influences of the motion and non‐smooth nature of the film surface upon the air stream are isolated and values of equivalent sand roughness are determined.
