Developed quasi-harmonic motions of a fluid film in a gas flow
Abstract
Quasi-harmonic wave motions of a thin fluid film flowing along a vertical surface under the action of gravity, capillary forces, and shear stress acting on the film-gas boundary are analyzed. Region of existence and spectral characteristics of quasi-harmonic wave solutions are found for various flow regimes of the film (e.g., with and against the gas flow).
