Abstract: The influence of gas flow on wave characteristics of liquid film for $\mathrm{Re}<15$ is studied. Optimal modes of liquid film flow in terms of countercurrent are considered. Wave shapes on free surface of liquid film in nonlinear approach are calculated.

Keywords: liquid film, countercurrent, shear stress, free surface, wave characteristics.
