      The paper examines the case of a rotordynamic analysis and subsequent rotodynamic testing conducted during the pre-order phase for a five-stage integrally-geared centrifugal compressor, which today is operating in a refinery ...
    • Hantz, Brian; Pettinato, Brian; Wang, Qingyu (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      Acceptance criteria for high-speed balancing of turbomachinery are specified in API standards based on either pedestal velocity or shaft displacement, and these are discussed in detail Pedestal velocities are measured using ...
    • Cloud, C. Hunter; Pettinato, Brian; Kocur, Jr., John (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      A re-examination of the well-known Ekofisk re-injection centrifugal compressor is presented Several opportunities makethis an ideal candidate to assess how well (or not) current design and analytical methods have evolved ...
    • Childs, Dara; Torres Rueda, Jose; Yang, Jing; Moreland, J. Alex (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      Test results are presented and compared for the following annular pump seal geometries: (a) a smooth-rotor/circumferentially-grooved stator (SR/GS) and (b) a smooth-stator/circumferentially-grooved rotor (GR/SS) The GR/SS ...
