    In this tutorial, we will address the basic characteristics of each of the components in a gas turbine (compressor, combustor, gas generator turbine, power turbine) and the impact of typical control limits and control ...
  • A Fresh Look at Containment Seals and Equipment 

    Carmody, Christopher; Smith, Richard (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
    The need for reliable and safe sealing of rotating equipment remains as a primary concern for industry. In situations where single mechanical seals were used the introduction of environmental and safety legislation brought ...
  • Examination of Methods of Dry Gas Seal Supply, Regulation, and Monitoring 

    Bakalchuk, Vladimir; Dwyer, Kevin; Hosanna, Rich; Chinnaswamy, Sreenivasulu; Eisenmann, Jr., Robert; McCraw, Jim (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
    Compressor Dry Gas Seal Failure is a common issue that affects Turbomachinery train availability. Since most turbomachinery trains are un-spared critical assets, unscheduled shutdowns have a major impact to the operating ...
  • Erosion Prediction of Gas Turbine Compressor Blades Subjected to Water Washing Process 

    Chiariotti, Alessandro; Borello, Domenico; Venturini, Paolo; Costagliola, Salvatore; Gabriele, Serena (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
    Blade fouling is a relevant problem in turbomachinery applications. It affects both compressors and turbines. In the first case, fouling can be generated by the presence of dust, ashes or brackish air (in offshore ...
  • Investigation and Resolution of Propane Compressor High Axial Position Alarm 

    Padmanabha, Sridhar Kuppa; Ng, Peck Lui (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
    Propane compressor in Propane Dewaxing Unit was experiencing intermittent high axial spikes coinciding with the chiller swing. The axial spikes were due to compressor surge caused by sudden drop in flow during chiller ...
  • Digitalisation in Medium Voltage Variable Speed Drive Systems to Increase Productivity in Oil & Gas Applications 

    Mandlekar, Umesh; Unruh, Alexander; Ganesan, Vijay (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
