    • Polytropic Efficiency Improvements and Sustenance on Centrifugal Compressor: Corrosion Erosion and Impact of Fouling 
      Zin, Tan Chek; Sing, Ng Wei; Tharakaram, Arni R.; Koguchi, Satoshi (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Case Study 5: This paper presents a case study on the rapid deterioration of compressor polytropic efficiency relating to systemic fouling and corrosion issues. Due to such issues, compressor service life was reduced from ...
    • Steam Turbine High Axial Displacement due to Governor Actuator Filter Clog 
      Jun, Ker Pin; Sing, Ng Wei (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
      The governor actuator for a steam turbine was observed to be hunting and failed to maintain stable operating speed. The steam turbine is used to drive a centrifugal compressor for H2 service in a recycle loop. The extent ...
    • Vibration Diagnostic of Steam Turbine Intermittent Rubbing 
      Jun, Ker Pin; Sing, Ng Wei (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
      A special purpose steam turbine has started to experience intermittent radial vibration spikes. The turbine is used to drive a Hydrogen Recycle Gas Compressor in Aromatics unit. No abnormality observed on the compressor ...
