description abstract | The stability conditions of a hollow rotor partially filled with a Newtonian liquid are investigated. The rotor is considered here to be a rigid body, supported by springs and dampers, and exposed to an external dynamic force in the shape of actions of the encountered liquid. The system has two degrees-of-freedom, defined by deflection in two mutually orthogonal fixed directions perpendicular to the rotor axis. The fluid motions are described by Navier-Stokes equations and comparison is made between the inviscid and viscous case in connection with their predictions of the stability conditions. Experiments are performed with two different rigidity ratios and results are found to be in agreement with theoretical data. | |
