    • Gomez, Bladimir (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
      In a major refinery there was excessive failures of centrifugal pumps, that cost the company millions of dollars every year. A new failure prevention strategy was developed to reduce the high cost of failures.
    • Postill, Julia; Drigant, Boris (Texas A&M University. Turbomachinery Laboratories, 2009)
      This case history discusses the upgrade of the #1 combination journal-thrust bearing assembly in the front standard of a 75 MW turbine/generator set. The existing taper land thrust plates experienced frequent failures and ...
    • Postill, Julia; Batiste, Emile; Husbands, Selcrest (Texas A&M University. Turbomachinery Laboratories, 2006)
      This case history discusses the upgrade of the #1 combination journal/thrust bearing assembly in an 80 MW turbine generator. The existing taper land thrust plates experienced frequent failures and the sleeve journal bearing ...
    • Lea, Fred (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)
      Sometimes when tasked with an effort that has been done many times before, the same path is followed over an over again. Sometimes the saying “Just because we have always done it that way, doesn’t mean it’s right” is very ...
    • Schmidt, John M. (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      A bolted raised face Joint (with O-ring gasket) was failure prone. An axisymmetric FEA (finite element analysis) of the Joint verified why: the flanges were not stiff enough (not thick enough); too much flange rotation ...
    • Strachan, Martin; Severs, Peter; Sharples, Andrew; Woolsey, Clive; Vickers, Tim (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 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 ...
    • Barbosa, Pedro Henrique de Alameda; Varella Guedes, André; Lima, Leonardo Montiero Barbosa; Freire, Ronaldo Lucas Alkmin (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      The purpose of this work is to present the first results of a practical approach developed for measuring the performance on energy and carbon of turbomachinery installed at offshore oil production plants, based on the ...
    • Smith, Patrick J.; Whalen, John; Pavelek, Dustin (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      The primary purpose of performing a lateral rotordynamic analysis for centrifugal compressors, steam turbines and other rotating machines is to ensure that there are no undesirable rotor/bearing performance issues that ...
    • Sorokes, James M.; Kuzdzal, Mark J. (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      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, ...

    • Schiavello, Bruno; Smith, Donald R.; Price, Stephen M. (Texas A&M University. Turbomachinery Laboratories, 2004)
      It is well documented that the proper operation of vertical centrifugal pumps is greatly dependent upon the entire pump/piping system, which includes the piping geometry and the system operating conditions. Oftentimes, ...
    • Hoppock, William G.; Van Bramer, Kenneth G.; Silvaggio, Joseph A. (Texas A&M University. Turbomachinery Laboratories, 1982)
      The intent of this paper is to describe various aspects of the application of abradable seals to industrial turbomachinery. Topics covered include sealing locations, materials, comparative studies and examples of the use ...
    • Vetter, Gerhard; KieBling, Ralph; Wirth, Wolfgang (Texas A&M University. Turbomachinery Laboratories, 1996)
      The reduction of abrasive wear and extension of the endurance of pumps requires a system analysis. Various pump types demonstrate different tribological systems under abrasive wear, which are basically dominated by sliding, ...
    • Guerra, Christopher; MacWilliams, Scott; Sorokes, James; Lupkes, Kirk (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 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 ...
    • Kerr, Tommy; Rimpel, Aaron; Simons, Sarah (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      During commissioning of an open-casing test rig, a loud (above 105 dB) high pitch “squealing” sound occurred at speeds above 3,000 rpm. All elements of the rig were removed except the bearings yet the noise persisted. ...
    • Gains-Germain, Andrea; Krish, Prem; Shirazi, Max (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
      Acid gas removal (AGR) using a high pressure amine solvent in a contactor tower is widely used to sweeten sour gas and render it suitable for commercial distribution. Acid gas removal is also common in other applications ...
    • Jungbauer, David E.; Blodgett, Larry E. (Texas A&M University. Turbomachinery Laboratories, 1998)
      Much work has been done over the years to predict the potential for acoustic fatigue in piping systems associated with pressure reducing systems in the design stage. However, an easily usable screening criteria for ...
