Abstract: | This paper studies the natural and forced oscillations of a deformed droplet of an inviscid liquid surrounded by a different
liquid and bounded in the axial direction by solid planes. In equilibrium, the droplet is a figure of revolution and the ratio
of its radius to height is significant. The equilibrium contact angle between the side surface of the droplet and the solid
surface is different from a right angle. The motion of the contact line is taken into account by setting an effective boundary
condition. It is shown that three characteristic ranges of natural frequencies exist. |
