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 ...
Resolution of Check Valve Failures in Reciprocating Compressors
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Discharge line check valves for reciprocating compressors are subjected to pressure pulsations, varying flow rates, and debris in the gas stream. Consequently, swing check, piston check, and modified plate-style compressor ...
What’s inside the ‘Box’ When Considering API Piping Plan 54?
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
What could typically drive support system selection towards Plan 54?A Plan 54 support system designation may be selected as it has specific advantages over Plan 53A, B, and C. The primary difference is that the circulation ...
Benefits of Physical Modeling in Large Pump Station Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This presentation explores common problems with pumps and pump stations, issues with pump intake hydraulics, HI standards, physical modeling – key considerations and presents the case study of Dallas Elm Fork WTP Pump Station 1.
ROTORDYNAMIC PERFORMANCE OF A FULLY-PARTITIONED DAMPER SEAL: EXPERIMENTAL AND NUMERICAL RESULTS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Balance piston seals restrict leakage at the discharge side of single shaft centrifugal compressors. There are multiple types of annular seals including labyrinth seals, textured surface seals such as honeycomb seals and ...
Dry Gas Seal Material Investigation for Enhanced Slow Roll & Wind-Milling Reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Dry gas seals, while ideally non-contacting, must reliably perform under all operating conditions encountered by a compressor, including those conditions which induce contact such as slow roll, turning gear, ratcheting, ...
