    • False And Misleading Sources Of Vibration. 
      Criqui, Albert F. (Texas A&M University. Turbomachinery Laboratories, 1994)
      Many false sources of "vibration" in rotating machinery of all types are described and discussed. The focus is on the practical distinction between actual vibration and spurious indications of vibration caused by problems ...
    • Fatigue Damage Of Steam Turbine Blade Caused By Frequency Shift Due To Solid Buildup - A Case Study. 
      Singh, Murari P.; Matthews, Terryl; Ramsey, Charles (Texas A&M University. Turbomachinery Laboratories, 1994)
      The case history is presented of a large steam turbine that experienced blade damage after about eight years of service. The probable cause and subsequent solution to the problem are addressed. A discussion of the metallurgical ...
    • General Purpose vs. Special Purpose Couplings. 
      Mancuso, Jon (Texas A&M University. Turbomachinery Laboratories, 1994)
      Flexible couplings are a vital part of a power transmission system. What type is selected, how much the coupling costs, and how much effort one spends on selecting a coupling and determining how it interacts with a system ...
    • Impeller Repair Techniques For Centrifugal Compressors. 
      Clayton, Charles R. (Russ); Klein, Darwin; Emerick, Mark F. (Texas A&M University. Turbomachinery Laboratories, 1994)
      Successfully repairing centrifugal compressor impellers requires careful consideration and planning. The selection of techniques for inspection, material, and welding procedures are determined by numerous factors. Original ...
    • Improving The Mechanical Reliability Of A Turbine-Compressor-Expander Used In A Nitric Acid Manufacturing Plant.
