Emerging Failures in Gas Turbine Engines Operating in Hot Environments
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Two (2) gas turbine engines operating offshore experienced Domestic Object Damage (DOD) failure with damaged blades in the HP compressor section.
The failures were caused by repeated use of a component undergoing wear ...
Operating With a Broken Pinion Teeth
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
There was a failure in the gear box of the main feed pump of the hydrocracker unit. As no spare was available, there was no immediate fix to the failure. A quick evaluation of the damage to the gear was done and an interim ...
sCO2 Compression
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Supercritical Carbon Dioxide (sCO2) power cycles are a transformational technology for the energy industry, providing higher thermal efficiency compared to traditional heat-source energy conversion including conventional ...
PROTOTYPE TILTING PAD THRUST BEARING WITH NOVEL CERAMIC MATERIAL FOR HARSH SERVICE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Product-lubricated pumping applications require extremely robust bearings, especially in the case of sand-loaded lubrication fluids. For high power/high speed pump applications, tilting pad bearings are the preferred bearing ...
What’s inside the ‘Box’ When Considering API Piping Plan 54
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
API Piping Plan 54 utilizes an external source to provide a clean pressurized barrier fluid to a dual pressurized mechanical seal designed to allow minimal leakage across the primary sealing interface into the process ...
METHODS TO DETERMINE AND SPECIFY ROTODYNAMIC PUMP DYNAMIC ANALYSIS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Vibration caused by resonance is an industry problem for new and retrofit applications that persists due to lack of specification and upfront analysis. To limit the chances of resonant vibration, dynamic analysis of the ...
A REVIEW OF AERODYNAMICALLY INDUCED FORCES ACTING ON CENTRIFUGAL COMPRESSORS, AND RESULTING VIBRATION CHARACTERISTICS OF ROTORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
There are several sources of non-synchronous forced vibration of centrifugal compressor rotors. Many of them are aerodynamic phenomena, created within the gas path of the compressor. Phenomena such as impeller stall, ...
