    • Thompson, W. E. (Texas A&M University. Gas Turbine Laboratories, 1972)
      The transformation between work and other forms of energy is accomplished in turbomachinery. The ability of a turbine to produce work when handling a compressible fluid and when taking either its axial or radial configuration ...
    • Borhaug, Jan; Mitchell, John (Texas A&M University. Gas Turbine Laboratories, 1972)
      Recent experiences with frequency spectrum analysis for onstream evaluation of mechanical performance are reviewed from a user's standpoint. Current practices of transducer selection and positioning, data acquisition and ...
    • Davis, H. M. (Texas A&M University. Gas Turbine Laboratories, 1972)
      The operation and maintenance of centrifugal compressors varies considerably depending upon the size, speed, horsepower, and type of driver. Typical centrifugal compressors vary from high speed, low flow applications to ...
    • Reddy, Ramana (Texas A&M University. Gas Turbine Laboratories, 1972)
      Sixteen centrifugal stages in two cases driven by a Rolls Royce AVON jet and a single stage power turbine compress natural gas of Mol Weight 23 from a pressure of 65 to 2000 psia. The rotating train, the coolers, the ...
    • Abramovitz, Stanley (Texas A&M University. Gas Turbine Laboratories, 1972)
      The basic and practical design concepts of fluid film bearings as applied to turbomachinery will be discussed. The discussion will cover specific applications that are representative of a wide range of conditions that can ...
    • Clapp, Allen M. (Texas A&M University. Gas Turbine Laboratories, 1972)
      A properly designed, installed, operated, and maintained lubrication system is necessary for reliable machine performance. In this paper the principles involved in the operation and maintenance of a system are emphasized. ...
    • Herbage, B. S. (Texas A&M University. Gas Turbine Laboratories, 1972)
      There are many approaches to the design of thrust and journal hearings for high speed turbomachinery, ranging from the simplest flat thrust bearings and plain journal hearings to the very sophisticated multiwedge designs ...
