Claims20
A turbine vibration reduction system, comprising:
- a nozzle;
- a bucket in operable communication with the nozzle;
- and
- a structure near the bucket having at least one opening configured to inject fluid into flow traveling past the nozzle and the bucket to disrupt formation of a vortex.

A turbine vibration reduction system comprising:
- a nozzle;
- a last stage bucket in operable communication with the nozzle;
- and
- a casing surrounding the last stage bucket having an opening therein located downstream of the last stage bucket being configured to inject fluid into flow having passed the last stage bucket to disrupt formation of a vortex in the fluid during operational conditions of the turbine conducive to vortex formation.
