The impact of vibrations on the dynamics of a system of two immiscible liquids filling a rotating container is studied experimentally. A horizontal cylindrical container is rotating at a rate sufficient for the liquids, whose densities are not equal, to become steadily distributed in the form of core and annulus. The vibrational motion of the container has a frequency virtually equal to that of rotation. It is demonstrated that at the coincidence of the frequencies the container’s oscillations lead to the transformation of the centrifugal field. As a result, the column of light liquid is shifted steadily in the rotating frame of reference. With the increase in the amplitude of vibrational forcing, in a threshold manner the liquid–liquid interface loses its axial symmetry, and a centrifugal wave emerges on it. The threshold of wave onset is determined by the dimensionless vibrational acceleration. The obtained results demonstrate a possibility to apply vibrations for the positioning of a liquid core in a rotating container and for the control of its dynamics.

实验研究了振动对填充旋转容器的两种不混溶液体系统动力学的影响。卧式圆柱形容器以足以使密度不相等的液体以芯和环的形式稳定分布的速度旋转。容器的振动运动的频率实际上等于旋转的频率。结果表明，在频率一致的情况下，容器的振动导致离心场的转换。结果，轻液柱在旋转的基准框架中稳定地移动。随着振动力振幅的增加，液-液界面以阈值方式失去其轴向对称性，并在其上产生离心波。波浪起伏的阈值由无量纲的振动加速度确定。所获得的结果表明，可以将振动应用于液体芯在旋转容器中的定位以及对其动力学的控制。
