Abstract

Based on the literature review, developed a mathematical model for calculating the parameters of the wave flow in the film contact apparatus. Based on the model set of critical layer thickness between the liquid and gas, its speed. Estimated in the frequency of waves in the film and compared with the experiments of other authors for the gravitational film. The model allows a qualitative assessment of wave motion.
