An Overview of the Design and Performance Testing of a 275 BAR Integrally Geared Supercritical CO2 Compressor for Power Generation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
An integrally geared compressor-expander (compander) for supercritical CO2 (sCO2) was developed to convert thermal energy to electricity. With operating pressures of 275 bar, this turbomachine represents the state of the ...
Materials And Coatings For Turbomachinery In Hydrogen Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Centrifugal compressors are commonly utilized for hydrogen compression in refineries for critical applications, and a potential “Hydrogen Economy� to lowering the carbon footprint on a worldwide scale will require ...
AN IMPROVED THRUST PREDICTION MODEL FOR HIGH PRESSURE MULTI-STAGE CENTRIFUGAL COMPRESSORS
(2022)
Axial thrust load predictions are an important aspect when it comes to predicting the performance of centrifugal compressors. The accurate prediction of axial thrust forces is necessary to size the appropriate balance ...
Prediction Of Lateral Vibration Behavior Of Integrally Geared Centrifugal Compressor During Synchronous Motor Startup By Transient Torsional-Lateral Coupled Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Startup transients of both torsional and lateral vibration behaviors of an integrally geared centrifugal compressor driven by a synchronous motor are examined by transient torsional-lateral coupled analyses, and the numerical ...
Predicting And Correcting Nonlinear Vibration Growth In Tilting Pad Journal Bearings Undergoing Large-Amplitude Whirl
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
When machines equipped with tilting pad bearings are well enough balanced to limit the journal whirl amplitudes to less than 40% to 50% of the bearing clearance, the bearing behavior can usually be considered linear and ...
Developing & Testing Components For More Reliable Linear Reciprocating Compression Of Hydrogen
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Southwest Research Institute® (SwRI®), ACI Services, Inc. (ACI), and Libertine FPE Limited collaborated to design and build a Linear Motor Reciprocating Compressor (LMRC) via a DOE-funded project with ACI cost share. The ...
Measurement And Calculation Of A Self-Equalized Tilting-Pad Thrust Bearing Under Static Misalignment
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Tilting-pad thrust bearings which include a self-equalizing feature, ensure reliable and safe operation especially under conditions on which misalignment between bearing and collar occurs. One common method to incorporate ...
An Objective Way To Account For Unbalance Vibration In Measured Rotor-Dynamic Data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This paper will illustrate a practical, objective and general method to calculate the unbalance and runout part of measured rotor-dynamic vibration data by a statistical method. Vibration measurements, as typically recorded ...
Thermo-Structural Analysis Of Steam Tracing Arrangements Applied To Pump Barrels
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Pumps steam tracing is widely used in Oil&Gas industry for critical services in which the process fluid requires a minimum temperature to avoid its crystallization during stand-by. This paper describes the process of ...
Rotordynamic Stability Of A Rotor With Three Open Impellers, Validated By Magnetic Bearing Exciter During Full Load Full Pressure (Flfp) Testing
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
As speed and power density increase, open (unshrouded) impellers are becoming more and more utilized in process gas compressors. Open impellers enable higher tip speeds and more aerodynamic head per stage than closed ...
