    • On-Stream Cleaning Of Turbomachinery 

      Turner, Brian (Texas A&M University. Gas Turbine Laboratories, 1973)
      On-stream cleaning is regularly practiced on the axial compressors of gas turbines and on steam turbines. Many other turbo machines could be cleaned in service. In fact, the limiting factor is not the machine type, but the ...
    • Some Metallurgical Considerations In Centrifugal Compressors 

      Cameron, Joseph A.; Danowski, Frank M. (Texas A&M University. Gas Turbine Laboratories, 1973)
      Consideration of the materials for use in rotating machinery must begin with careful study and appraisal of expected operating conditions. In the discussion which follows, attention is concentrated on centrifugal compressors, ...
    • Case Histories Of Specialized Turbomachinery Problems 

      Wachel, J. C.; Von Nimitz, Walter; Szenasi, F. R. (Texas A&M University. Gas Turbine Laboratories, 1973)
      Vibration problems in turbomachinery occur due to many factors. Some of the problems could have been prevented if more detailed design analyses were performed. Other times the problems occur due to design extrapolations ...
    • Real Time Spectral Analysis-Taking The Mystique Out Of This Valuable Maintenance Tool 

      Palm, Jon E. (Texas A&M University. Gas Turbine Laboratories, 1973)
      A new "yardstick" for measuring rotating machinery vibration is seen in the real time spectrum analyzer. This paper presents some actual case history data that was analyzed using a real time spectrum analyzer. The object ...
    • Maintenance Techniques For Turbomachinery 

      Nelson, William E. (Texas A&M University. Gas Turbine Laboratories, 1973)
