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, ...
Accidental Excitation of Acoustic Resonances from Balance Holes on Rotating Disk
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
During commissioning of an open-casing test rig, a loud (above 105 dB) high pitch “squealing” sound occurred at speeds above 3,000 rpm. All elements of the rig were removed except the bearings yet the noise persisted. ...
Significant MTBF improvement of a water injection pump application by using diamond coated seal face material technology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
A well-known oil company in Oman is producing crude oil using “produced water injection” as their favorite Enhanced Oil Recovery (EOR) techniques. This nasty water is reinjected into the well by high-pressure multistage ...
PRECISION GROUTING OF TURBOMACHINERY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Rotating equipment being installed in industrial environments, including refineries and chemical processing plants, are critically aligned with exact tolerances. When in operation, this equipment experiences heavy dynamic ...

Effect of swirl canceller on impeller exitation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
This case study is concerned with effect of the swirl canceller for impeller excitation force of integrally geared compressor. The 5th stage shaft vibration of booster air compressor showed abnormal behavior as the discharge ...
