Results of a study of the height of liquid films flowing concurrently with an air stream in a horizontal channel are presented. If three‐dimensional waves exist at the interface, the dimensionless film height h + = hu */ v , defined in terms of the friction velocity and the kinematic viscosity of the liquid, is primarily a function of the liquid Reynolds number.
