FACTORS INFLUENCING THE ACCURACY OF TURBOMACHINERY AERODYNAMIC PERFORMANCE PREDICTIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
This tutorial delves into the factors that impact the accuracy of turbomachinery performance predictions. The discussion is broken down into three parts… the influence of engineering tools / procedures, the impact of the ...
Considerations for Couplings in Motor Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
This paper addresses the special considerations required to select special purpose couplings for different types of motor designs and those provided with adjustable frequency drives (AFD), with an emphasis on API 671 ...
TECHNICAL TRENDS FOR ELECTRICAL COMPRESSOR DRIVE SYSTEMS ABOVE 30,000 hp
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
The presentation will give and overfiew of electrical drive technology that can be used to drive compressors in the power range above 30,000 hp. Technical trends will be discussed with a focus on variable speed drives (VFD) ...
Lessons learned solving sliding vane compressor vibration problems
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
A benefit claimed for vane compressors is they do not have vibrations problems that are experienced by other positive displacement machines. This case study demonstrates high vibration and fatigue failures on a sliding ...

Two-thirds of the pipelines in North America are transporting non-crude hydrocarbon products such as NGL, diesel, avaiation fuel, Copyright© 2020 by Turbomachinery Laboratory, Texas A&M Engineering Experiment Station ...
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. ...
Case Study: Lateral Analysis Fixes a Multi-Stage Diffuser Boiler Feedwater Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
History gets confusing. A lot of emails, vibration reports, and attempted fixes over the years. Customer spent 3 years working closely with OEM, Pump was shipped back to OEM for additional testing. OEM design suggestions ...
