【 摘 要 】

The effect of large-amplitude translational vibrations on the dynamics of a two-phase system (light cylinder in liquid or two immiscible liquids, placed in a rotating cylindrical cavity) is studied experimentally. The experiments are run at high rotation rate, when under the action of centrifugal force the light phase is located near the rotation axis. Vibrations are perpendicular to the rotation axis and their frequency is close to the rotation rate. When the frequencies coincide, the vibrations change the centrifugal field configuration. The light phase column shifts stationary in the rotating frame of reference.
