The paper presents the results of tests and theoretical considerations concerning determination of the liquid film thickness under the cocurrent two-phase downward flow of gas and very viscous liquid. Influence of viscosity changes on undulation of the liquid film surface and changes of its thickness has been determined. Relationships for determination of the flowing liquid film thickness in the two-phase gas-liquid flows have been formulated.
