Abstract:
The transformation of a solitary two-dimensional wave into three-dimensional waves on a falling liquid film was studied using the high-speed method of laser-induced fluorescence allowing high spatial and temporal resolution, which allows measuring the thickness of liquid films with high spatial and temporal resolution, the process of decay of a solitary two-dimensional wave into three-dimensional waves in case of film flow along a vertical plate. It was shown that the package of three-dimensional waves resulting from the decay of a solitary two-dimensional wave had a strong perturbing effect on the falling film and leads to the formation of rivulets on its surface.
