Abstract

A physical model for the hydrodynamic mechanisms associated with gravity rolling waves in thin liquid films is presented. The model is based on a periodical distortion of the hydrodynamic boundary layer in the wave front, followed by a recovery process in the wave trail. One input (frequency) is required for prediction of all other wave variables at the developing region. At the developed region, energy considerations provide an additional relationship for predicting the waves frequency. Thus, a closed-form solution is obtained. The agreement with experimental data is satisfactory for wide ranges of liquid flow rates and inclination.
