Аннотация: Results of experimental investigation of regular wave conditions for straight rivulets falling down a vertical plane are presented. Field measurements of the local thickness of rivulets were carried out with the help of laser-induced fluorescence. Data on the wave structure of rivulets is shown in a wide range of frequencies of regПоказать полностьюular waves for different Reynolds numbers of the flow and contact wetting angles. It was observed for all studied wave conditions that transverse width of rivulets and wetting angles are insensitive to the phase of propagating waves. Moreover, it was found that the wave structure of rivulets differs significantly for the cases of low and high values of the contact angle. © 2010 Pleiades Publishing, Ltd.
