... on the stability of the rotor-annulus systems are invariably neglected. In modern turbomachinery, two essential narrow annular gaps exist, applying fluid-film forces and moments on the rotating shaft [3, 9, 10]. First, annular seals or damper seals and second, journal bearings which are either oil or media...
