The current paper studies the influence of annular seal flow on the transient response of centrifugal pump rotors during the start-up period.
A single rotor system and three states of annular seal flow were modeled.
These models were solved using numerical integration and finite difference methods.
A fluid-structure interaction method was developed.
In each time step one of the three annular seal models was chosen to simulate the annular seal flow according to the state of rotor systems.
The objective was to obtain a transient response of rotor systems under the influence of fluid-induced forces generated by annular seal flow.
This method overcomes some shortcomings of the traditional FSI method by improving the data transfer process between two domains.
Calculated results were in good agreement with the experimental results.
The annular seal was shown to have a supportive effect on rotor systems.
Furthermore, decreasing the seal clearance would enhance this supportive effect.
In the transient process, vibration amplitude and critical speed largely changed when the acceleration of the rotor system increased.
