  • Leontiev M.K., Davidov A.V., Degtiarev S.A., Ivanov A.V., Dynamics of rotor systems with fluid annular seals
    Annular seals The mathematical model of the hydrodynamic annular seal- the floating ring and methodology for investigation of the fluid pumps rotor dynamics is presented. The algorithm to determine hydrodynamic force and reaction of a seal as a part of the rotor system is given. By example of the high speed model rotor with the annular seal, the motion of the rotor shaft and the ring is investigated, the rotor stability boundary is obtained.
