    • Lienau, Wolfram; Sandford, Peter; Deger, Yasar (Texas A&M University. Turbomachinery Laboratories, 2005)
      It should be an objective to predict bearing housing vibrations by means of finite element methods and avoid them in the design phase rather than to go in for corrective actions on the test bed or in the field. Bearing ...
    • Bibet, Pierre-Jean; Quiox, Bernard (Turbomachinery Laboratory, Texas A&M University, 2012)
      In 2011, for the first time Hybrid Multiphase Pumps have been deployed on the seafloor. This was Offshore Angola, at 800m Water Depth, to ensure the full field development of Pazflor Deep Sea Project by pumping the viscous ...
    • Kocur, John A.; Muench, Maximilian G. (Texas A&M University. Turbomachinery Laboratories, 2012)
      The popularity of VFD motors in compressor trains has increased in recent years. Increased process flexibility is a primary consideration for implementation of VFD systems. However, this comes at a cost of increased ...
    • Brun, Klaus; Nored, Marybeth G.; Kurz, Rainer (Texas A&M University. Turbomachinery Laboratories, 2013)
    • King, T. L.; Capitao, J. W. (Texas A&M University. Gas Turbine Laboratories, 1975)
      Recent test programs on Kings bury type tilting pad thrust bearings have altered application data and required the use of larger thrust bearing sizes with correspondingly larger oil flows and increased power loss. These ...
    • Finck, Edward J. (Texas A&M University. Turbomachinery Laboratories, 1983)
      Frequently, large swings in operating conditions are specified when purchasing turbines. Although the objective of these operating conditions may be to insure conservatism, they also may result in turbine designs which ...
    • Schiffer, Donal M.; Syed, Asadullah (Texas A&M University. Turbomachinery Laboratories, 2006)
      A standardized and cost-effective risk assessment toolkit is described in this paper to comprehensively analyze centrifugal compressor impellers under steady and dynamic loads. The first step in this process occurs in the ...
    • Moyroud, Francois; Alas, Pascal; Libeyre, Francois (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      The impeller of a natural gas pipeline compressor failed at the junction between the blade trailing edge and the hub. A root cause analysis showed the machine had been operated beyond the compressor map right limit during ...
    • Frier, Sean; Sorokes, James M.; Burkardt, Nicholas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      This tutorial provides an overview of the manufacturing processes used to build centrifugal compressor impellers and how the various processes can impact the performance of these critically important components. Comments ...
    • Frier, Sean; Sorokes, James M.; Burkardt, Nicholas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)
      This tutorial provides an overview of the manufacturing processes used to build centrifugal compressor impellers and how the various processes can impact the performance of these critically important components. Comments ...
    • Clayton, Charles R. (Russ); Klein, Darwin; Emerick, Mark F. (Texas A&M University. Turbomachinery Laboratories, 1994)
      Successfully repairing centrifugal compressor impellers requires careful consideration and planning. The selection of techniques for inspection, material, and welding procedures are determined by numerous factors. Original ...
    • Dyson, Gary (Texas A&M University. Turbomachinery Laboratories, 2005)
      The vibration of centrifugal pumps, running at both best efficiency point (BEP) and at low flow, is of interest to both pump designers and users. This vibration is responsible for the poor seal and bearing life and reduced ...
    • Iwamoto, Shinji; Yoneda, Keizo; Tokuyama, Shinichiro; Higuchi, Hirofumi; Nakaniwa, Akihiro; Barrington, Bryan (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      In the case of centrifugal compressors, minor non-uniform flow upstream of the impeller is induced by an asymmetrical configuration in the circumferential direction at the compressor suction casing. This non-uniform flow ...
    • Ifrim, Costin (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
      By design, the operation of a large 3MW permanent magnet motor-driven pump system has the potential to improve system efficiency and reliability to lower operator costs. Subsea electrical system design and motor performance ...
    • Koring, Rolf (Texas A&M University. Turbomachinery Laboratories, 2003)
      There are differences between European and US bearing metals. This paper shows the mechanism for improving the properties of bearing alloys and the environmental problems that have arisen so far in this connection. Since ...
    • Buck, Gordon S.; Chen, Tsu Yen (Turbomachinery Laboratory, Texas A&M University, 2010)
      Heat soak is defined as heat transfer from the metal of a seal chamber to the fluid within the seal chamber. Many variables affect heat soak including materials, surface configurations, and film coefficients. Heat soak can ...
    • Martin, Jose; Riché, Chris (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Extracting hydrocarbon products in oil sand formations requires high pressure to drive fluid out of the formation and to move the products out to production. The pump models that fit this operating envelope are not common ...
    • Salant, Richard F.; Key, William E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      The mechanical seal manufacturer can now offer the user new seal designs quickly and efficiently, and can respond to trouble shooting requests rapidly, through the use of modern, computerized, seal design techniques. In ...
    • Manning, Frank E.; Mosher, Rod; McCullough, Doug (Texas A&M University. Turbomachinery Laboratories, 1996)
      The cost of high pressure gland water and increasing environmental concerns have made the use of flushless mechanical seals attractive in many slurry applications. One such application exists at Syncrude Canada Lts (SCL). ...
    • Murphy, Brian T.; Vance, John M. (Texas A&M University. Turbomachinery Laboratories, 1981)
      A number of the computer programs for rotordynamic stability and critical speed prediction in common use during recent years have been based on the works of Myklestad, Prohl and Lund. Programs of this type, called transfer ...
