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 ...
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 ...
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 ...
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, ...
Optimizing compressor packing designs by predicting rod temperatures.
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
The pressure packing is a critical component of every reciprocating compressor. High wear leads to increased process gas leakage rates which can result in a compressor shutdown. Excessive leakage can even cause fugitive ...
High Strength Material for Hydrogen Service, an Experimental Investigation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
As an energy source, hydrogen has been a topic of discussion for some time. To support future energy demands, efficient means ofhydrogen compression will be required. Centrifugal compression may play a larger role in a ...
HYDROGEN-COMBUSTION AND COMPRESSION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Recently, the use of hydrogen-natural gas mixtures as a fuel, but also as a means of storing and transporting hydrogen from surplus electricity as a result of renewable energy production has drawn significant attention. ...
Development and Testing of a Supercritical CO2 Compressor Operating Near the Dome
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
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 ...
