Capillary waves on a falling film
Guangzhao Zhou, Andréa Prosperetti
Abstract
Large waves forming on the surface of a liquid film flowing down an inclined plate are accompanied by a steady train of capillary waves. A study shows that the wavelength and spatial attenuation of these waves are consistent with the properties of linear viscocapillary waves having the same phase velocity as the large wave.
