... fits, in contrast butt joint, Hirth, and Curvic couplings have interface contacts in the axial direction. A conventional practice is to treat interference fits as continuous connections in rotordynamic shaft models. However, this may introduce significant inaccuracies by neglect of the local interface...

... and the proposed working fluid properties. High-level flow-path design parameters, such as pitch diameter and number of stages, are established considering a trade-off between weight and footprint, turbine efficiency and rotordynamics. Rotordynamic stability is assessed considering the high fluid density related...
