Abstract
The structure of rimming flow in a horizontal rotating cylinder subjected to vibration is experimentally investigated. Under vibration liquid performs oscillations. In the resonant domain oscillations have a form of progressive two-dimensional azimuth wave which generates averaged flow in the direction of its propagation. It is found that the plane motion is unstable to the spatially periodic vortical flow appearance. The transition to the vortical flow is determined by the oscillatory liquid flow instability in viscous Stokes layer near cylindrical wall. The threshold of 2D flow instability and the structure of overcritical flows in a wide range of dimensionless parameters are investigated.
