BEHAVIOUR OF SOLID INCLUSIONS IN THE CYLINDER WITH LIQUID SUBJECTED TO ROTATIONAL OSCILLATIONS
The behavior of light cylinder in the horizontal cylindrical cavity under its rotational oscillations is experimentally investigated. The cavity is filled with liquid (Glycerol or sunflower oil). The behavior of the body is investigated as function of frequency and amplitude of vibration. The gap between the body and the wall of the cavity comparable with the thickness of the Stokes layer appears under vibrations. The dependence of the threshold of the repulsion (critical value of vibrational parameter) on the dimensionless frequency and the dimensionless gap width on the magnitude of the vibrational parameter are investigated
