Torsional Rotordynamics of Machinery Equipment Strings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Root Cause Failure Analysis for Machinery and Piping Part 1: Introduction to RCFA
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
MODELING OF PRESSURE DYNAMICS DURING SURGE AND ESD
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Centrifugal compressors operability at low flow is normally limited by the onset of surge that occurs when operating near maximum achievable pressure rise. Surge is characterized by large amplitude and periodic pressure ...
IMPACT OF PIPING IMPEDANCE AND ACOUSTIC CHARACTERISTICS ON CENTRIFUGAL COMPRESSOR SURGE AND OPERATING RANGE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The performance of a centrifugal compressor is usually defined by its head versus flow map, limited by the surge and stall regions. This map is critical to assess the operating range of a compressor for both steady state ...
A PROBABILISTIC APPROACH FOR COMPRESSOR SIZING AND PLANT DESIGN
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Equipment sizing decisions in the Oil and Gas Industry often
have to be made based on incomplete data. Often, the exact
process conditions are based on numerous assumptions about
well performance, market conditions, ...
STALL INDUCED AERODYNAMIC FORCING AND ROTOR VIBRATIONS IN A MULTISTAGE CENTRIFUGAL COMPRESSOR
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The Oil & Gas industry is looking with increased interest
at solutions for improving operating flexibility of centrifugal
compressors. The stable operation of a compressor stage or
machine is generally limited at the ...
EFFECTS OF SUPPORT STRUCTURE DYNAMICS ON CENTRIFUGAL COMPRESSOR ROTOR RESPONSE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Accurate modeling of complicated dynamic phenomena characterizing rotating machineries represents a critical aspect in the rotor dynamic field. A correct prediction of rotor behavior is fundamental to identify safe operating ...
Innovative Design in Expander Wheel-Shaft Attachment Replaces Hirth Coupling for High Speed, High Temperature and High Power Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Although this Case Study is focused on an Expander-Generator unit in a geothermal application, it’s findings can be used in all turbomachinery applications where other conventional shaft-wheel attachments are causing ...
Large Steam Turbine Vibration Resonance of Pedestal and Linkage System RCA, Detail Vibration Investigation/Measurement at Site and Countermeasures
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
A Large Steam Turbine had been in operation for several years and this
turbine experienced the wear damage of governor linkage.
Then, measured the vibration velocity profile on Governor side pedestal
to identify the ...
INFLUENCE OF IMPELLER SUCTION SPECIFIC SPEED ON VIBRATION PERFORMANCE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The most commonly used hard limitation for pump suction specific speed is 11,000 (US units). This hard limit grew out of the recommendations from a 1982 reliability study by J.L. Hallam (Hallam 1982). Concomitant testing ...
