Case Study of Pump Failure Due to Rotor-Stator Interaction
Fluiddynamic interaction between rotor and stator generates local pressure fluctuation and can be a cause ofstructural vibration of turbomachines. The interaction produces a spatial distribution of pressure fluctuation with a certain diametrical mode and propagating speed, known as rotating pressure...

| description | Fluiddynamic interaction between rotor and stator generates local pressure fluctuation and can be a cause ofstructural vibration
of turbomachines. The interaction produces a spatial distribution of pressure fluctuation with a certain diametrical mode and
propagating speed, known as rotating pressure field. When the frequency and mode of a rotating pressure field coincide
with those of the structural vibration, a fluid-excited resonance takes place, leading to eventual severe structural damage. An
example of such damage is described in detail using the case of PLR pump failure of a BWR plant. |
