Аннотация: Synchronous macrophotography and high-speed video filming data were used to investigate pinch-off, oscillations and short capillary surface waves of a free falling droplet. Planning of the experiment was carried out taking into account a free surface energy resulted from anisotropy of atomic-molecular interactions in a thin subsurface layer with a thickness of the order of the molecular cluster size (10-6 cm). During a drop pinch-off, fast process of the free surface energy release leads to formation of large-amplitude oscillations and short capillary waves. Theoretical model of droplet oscillations based on the Euler equations was developed.
