Stability of Steam Whirl Exciteted Laval Rotor

The phenomenon of steam whirl arises in an axial flow machine when a radial displacement of the shaft takes place as a result of different leakage losses around its circumference. A produced resultant force is perpendicular to the displacement. In the following a simple means of calculating this excitation force will be derived and it will be shown how this force influences to the vibration behaviour of the rotor.
