Rotordynamic fluid forces coupled with flow instabilities (i.e., impeller/diffuser rotating stall and rotating cavitation) in turbomachines were examined. Variations of fluid forces arisen from the flow instabilities have the similar characteristics, even if under the rotating stall or the rotating cavitation. The phase of the whirling fluid force vector changes by π around the natural frequency of flow instabilities. Kuramoto’s nonlinear model could explain well the synchronization of the whirling motion with the rotating flow instabilities.
