Abstract
The motion of a liquid drop under the action of acoustic vibration is studied for two limiting cases: the high-frequency case, when the effect of viscous forces can be ignored, and the low-frequency case, when the viscosity is significant. Equations describing the motion of a drop in an axially symmetric capillary with a varying cross section are derived by taking into account the hysteresis of the wetting angle. Numerical calculations are performed for cylindrical, conic, and corrugated capillaries.
