摘要

The flow in the gap between two cylinders with the inner one subject to high frequency vibrations is investigated. The equations for the man and pulsating components of hydrodynamical fields are formulated taking into account the pulsating transport of the mean vorticity. It is shown that in the cas4e of oscillations of circular polarization the main flow is axisymmetrical. Linear and nonlinear stability of the main flow is treated numerically. It is found that without taking into account the pulsating transport the problem is equivalent to the Couette-Taylor problem for two co-rotating cylinders.
