Understanding Design Parameters That Affect Thermal Stability of High-Speed Turbo Machinery (Also Known As the Morton Effect)
MetadataShow full item record
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 heating of shaft journals. The industrys inability to reliably predict this phenomenon has caused both plant start-up delays and shutdowns due to machinery vibration. The multiple case studies that will be presented assess this problem and summarize the solutions that were developed, tested and ultimately implemented to address the Morton Effect.
