The behavior of a cylindrical solid of nonaxisymmetric cross section in a horizontal cylindrical cavity filled with a viscous incompressible fluid under rotational vibrations is experimentally investigated. The effect of the vibrational suspension of a heavy nonaxisymmetric cylinder near the bottom of the vibrating cavity was found and studied at a distance comparable with the Stokes layer thickness. The character of oscillations of the cylinder and its interaction to the wall of the cavity is studied by high-speed video registration of process.
