In various industrial applications, there is a need
for higher speed, yet reliably operating rotating
machinery. A key factor in achieving this type of
machinery continues to be the ability to accurately
predict the dynamic response and stability of a
rotor-bearing-seal system. In operation, the rotor
undergoes bending and torsional vibration. The
vibration of a rotor depends upon its geometry and
type of support, as well as on the excitation forces.
One of the most important sources for excitation is
the flow through labyrinth seals. The gas flow
through the seals, primarily intended for...
