THE USE OF ACOUSTIC COMB FILTERS TO AVOID CENTRIFUGAL COMPRESSOR DISCHARGE BLADE-PASS PULSATION INDUCED PIPING VIBRATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Centrifugal compressor blade-pass interaction periodic pulsation can cause acoustic resonance conditions and pipe vibrations in the suction and discharge lines of the compressor. A series of two or more progressively placed ...
ACCELERATED TEST VALIDATION USING PRINTED POLYMER COMPONENTS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This paper describes efforts undertaken to increase the use of non-metallic components in research and development as well as component/stage validation testing. The switch to non-metallic or polymer components was driven ...
Overcoming Failure of Synchronous Motor Driven Compressor Train by Application of Controlled Slip Clutch
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study describes failure incident of a centrifugal compressor, its root cause investigation, and countermeasure implementation. An integrally geared centrifugal air compressor driven by a synchronous motor failed ...
DEVELOPMENT OF ROTOR CONTACT DETECTING SYSTEM FOR DRY SCREW COMPRESSOR
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
DRY screw compressors have the characteristics of a positive displacement typerotary compressor, are used in a wide range of applications. DRY screw compressors are often treated as one of the important equipment inplants. ...
Modernization of 75 year old Turbo Generator Emergency Trip System
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study presents lessons learned during the retrofit of two 75-year old Turbo Generator (TG) overspeed trip systems to meet the latest edition of API 612. The effort was initiated due to reliability issues with the ...
Why combustion components are particularly suitable for harvesting the benefits of additive manufacturing
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This paper focuses the use of additive manufacturing (AM) for the production of gas turbine (GT) combustion system components. It discusses how AM methods are being employed to improve the reliability and thermo-mechanical ...
Integrity Management of Safety Critical Rotating Equipment and Systems
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Safety Critical Elements (SCEs) are the equipment and systems that provide the basis of risk management associated with Major Accident Hazards (MAHs). A SCE is classified as an equipment, structure or system whose failure ...
A Novel Method for Evaluating Sideload Compressor Thermodynamic Performance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
A method has been developed that allows reasonably accurate sectional performance evaluation of sideload compressors based upon only external measurements available from the streams entering and exiting the compressor ...
A REVIEW OF AERODYNAMICALLY INDUCED FORCES ACTING ON CENTRIFUGAL COMPRESSORS, AND RESULTING VIBRATION CHARACTERISTICS OF ROTORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
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, ...
Turbo Tut - Performance of Industrial Gas turbines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Industrial gas turbines have performance characteristics that distinctly depend on ambient and operating conditions. Application of these gas turbines, as well as the control and condition monitoring, require to consider ...
