Abstract
Surface deformation of a liquid film falling over a vertical heated plate is being studied. The equation describing a change in film thickness was obtained in long-wave approximation with consideration of small surface perturbation. Approximated analytical solution for distribution of temperature within a film and surface perturbation was obtained for the case of weak heat transfer between liquid and gas and different thermal conditions. Dimensionless criteria determining surface deformation of a film were revealed and their effect on the solution obtained was analyzed.
