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...
