    • Application Of High Speed And High Performance Fluid Film Bearings In Rotating Machinery. 
      Zeidan, Fouad Y.; Paquette, Donald J. (Texas A&M University. Turbomachinery Laboratories, 1994)
      Some of the critical parameters in the design and application of high performance fluid film bearings are emphasized. The limitations and problems associated with high speed and highly loaded bearings will be discussed. ...
    • Design And Application Of Squeeze Film Dampers In Rotating Machinery. 
      Zeidan, Fouad Y.; Andres, Luis San; Vance, John M. (Texas A&M University. Turbomachinery Laboratories, 1996)
      There are common misconceptions and occasional misapplications associated with squeeze film dampers. The authors have worked for more than 25 years researching, experimenting, and applying this subject matter to all types ...
    • Design, Analysis, And Testing Of High Performance Bearings In A High Speed Integrally Geared Compressor. 
      Chen, Wen Jeng; Zeidan, Fouad Y.; Jain, Dilip (Texas A&M University. Turbomachinery Laboratories, 1994)
      Analysis, design, and optimization of high performance journal and thrust bearings in a high speed integrally geared compressor are described. The high speed and relatively small bearing size stretches the applicable limits ...
    • The Design, Application, And Operation Of High Efficiency Turboexpanders In Process Plants. 
      Kardine, William A.; Agahi, Reza R.; Ershaghi, Behrooz; Zeidan, Fouad Y. (Texas A&M University. Turbomachinery Laboratories, 1996)
      Turboexpander thermal efficiency is an important parameter in the process design of hydrogen purification plants. When a process requires low flow and high head, expander thermal efficiency can only be improved by increasing ...
    • Electric Shaft Currents In Turbomachinery. 
      Vance, John M.; Palazzolo, Alan B.; Zeidan, Fouad Y. (Texas A&M University. Turbomachinery Laboratories, 1987)
      Electrical damage to turbomachinery parts has caused a number of machinery failures and many hours of costly downtime. The problem of electrical voltages and currents being generated in non-electrical machines has puzzled ...
    • Experience In The Use Of Flexure Pivot Tilt Pad Bearings In Boiler Feed Water Pumps 
      Kepple, W. E.; Read, Dave W.; Zeidan, Fouad Y.; Paraskevakos, Christian; Dawson, Matthew P. (Texas A&M University. Turbomachinery Laboratories, 1998)
      Boiler feedwater (BFW) pumps are among the most critical rotating equipment in power plants. The bearings in these pumps must be able to attenuate rotor vibrations and other hydraulic forces while still maintaining a high ...
    • Fluid Film Bearing Fundamentals And Failure Analysis. 
      Zeidan, Fouad Y.; Herbage, Bernard S. (Texas A&M University. Turbomachinery Laboratories, 1991)
      Fluid film bearing technology is presented in this tutorial as it applies to turbomachinery equipment. The focus here is on the practical aspects of fluid film journal bearings, as opposed to theoretical analysis. Failure ...
    • The Use Of Honeycomb Seals In Stabilizing Two Centrifugal Compressors. 
      Zeidan, Fouad Y.; Perez, Robert X.; Stephenson, E. Morris (Texas A&M University. Turbomachinery Laboratories, 1993)
      The stabilizing effects achieved by replacing labyrinth seals with honeycomb seals are described. Although honeycomb seals have been used for some time in high pressure compressors and other turbomachinery applications, ...
    • Vibration And Eccentricity Measurements Combined With Rotordynamic Analyses On A Six Bearing Turbine Generator. 
      Gruwell, David R.; Zeidan, Fouad Y. (Texas A&M University. Turbomachinery Laboratories, 1998)
      This lecture discusses how the vibration characteristics and eccentricity measurements were combined with rotordynamic analyses to help improve the reliability of a turbine generator unit. It also explains certain ...
