Understanding Design Parameters That Affect Thermal Stability of High-Speed Turbo Machinery (Also Known As the Morton Effect)
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
At present, there are no commercially available codes in industry that have proven to reliably predict a rotors sensitivity to the Morton Effect. The Morton Effect refers to synchronous rotor instability due to non-uniform ...
Impeller High cycle fatigue failure on a Natural Gas Pipeline Compressor Following Choked Flow Operation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The impeller of a natural gas pipeline compressor failed at the junction between the blade trailing edge and the hub.
A root cause analysis showed the machine had been operated beyond the compressor map right limit during ...
Steam Turbine Reoccurring Rubs, Troubleshooting and Corrective Action
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Rubs in steam turbines can be especially difficult to diagnose because the vibration signature can manifest differently depending on the location, severity, rotordynamics, machine design and bear similarities to other ...
High Vibration Due to Steam Turbine Deposits
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This presentation provides a case study how to correctly deal with increased vibration on a steam turbine that drives a compressor. After the machine had not operated for a week, vibration level increased 5 times during ...

It is shown as the outline in this short course that the role of steam turbine, history, classification, basic structure, components and their function, manufacturing and design process and control system. And also, the ...
Preventing a Major Wreck on a New Reciprocating Compressor: The importance of commissioning testing
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
During commissioning testing of three new reciprocating compressors a fault was detected requiring the testing to be stopped. Debris was found in the bearing resulting in minor damage due to the early indication from the ...
