    • An Overview of the Design and Performance Testing of a 275 BAR Integrally Geared Supercritical CO2 Compressor for Power Generation 
      Wilkes, Jason C.; Pelton, Robert; Wygant, Karl (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)
      An integrally geared compressor-expander (compander) for supercritical CO2 (sCO2) was developed to convert thermal energy to electricity. With operating pressures of 275 bar, this turbomachine represents the state of the ...
    • Application and Design of Integrally Geared Compressors 
      Wygant, Karl; Bygrave, Jonathan; Bosen, Werner; Pelton, Rob (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Tutorial 7: Integrally geared compressors (IGC’s) are common in plant/instrument air service as well as air separation applications, and continue to gain acceptance over a wide range of other applications. An IGC can achieve ...
    • Manufacturing and Testing Experience with Direct Metal Laser Sintering for Closed Centrifugal Compressor Impellers 
      Allison, Timothy C.; Rimpel, Aaron M.; Moore, J. Jeffrey; Wilkes, Jason C.; Pelton, Robert; Wygant, Karl (Texas A&M University. Turbomachinery Laboratories, 2014)
      Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that utilizes a high-powered laser to build up a metal part by selectively melting thin layers of metal powder. This process is attractive for the ...
    • Overview of Turbomachinery for Super-Critical CO2 Applications 
      Wygant, Karl; Allison, Tim; Pelton, Robert; , (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      Cycles involving super critical carbon dioxide (sCO2) have the potential to increase system efficiencies well beyond current industry norms. Research on advanced direct and indirect cycles is ongoing in national labs and ...
    • Rotor-Bearing Dynamics of Integrally Geared Turbomachinery 
      Wygant, Karl; Robertson, Chad; Li, Fang (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This tutorial focuses on the rotordynamic characteristics of integrally geared compressors and expanders. Although the focus is for turbomachinery the topics discussed also apply to industrial gearing. The topics covered ...
