    • Deo, Prafulla; Gowaikar, Mohan N. (Texas A&M University. Turbomachinery Laboratories, 2005)
      Most of the water supply schemes use electrical power in large quantities. As such, optimization is needed for reducing life cycle cost of the entire establishment in terms of capital cost, minimum downtime, and maximum ...
    • Talbot, Robert (Turbomachinery Laboratory, Texas A&M University, 2011)
    • Buck, Gordon S. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
      Numerous studies have shown that mechanical seal reliability is related to the state of the fluid between the seal faces. In turn, the fluid state depends on the seal face temperature. Unfortunately, calculating the seal ...
    • Breslin, Mark T. (Texas A&M University. Turbomachinery Laboratories, 1989)
      Unless the utility industry is prepared as a whole to commit a very large dollar amount to the purchase of new heavy wall castings for turbine casings and valve chests, the use of the art of repair for existing castings ...
    • Kleynhans, George; Pfrehm, Gary; Berger, Heinz; Baudelocque, Luc (Texas A&M University. Turbomachinery Laboratories, 2005)
      The reciprocating compressor and the traditional centrifugal compressor have been the workhorses of the natural gas industry. However, new demands placed on gas distribution infrastructure by spot market activity necessitates ...
    • O'Brien, Jonathan; Kalfrin, Brian (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
    • Lee, Woonsil; Kim, Chi Hyuk; Lee, An Sung (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      On September 2013, a centrifugal heat-pump compressor began showing an abnormal temperature rise in its tilting pad journal bearing (DE-side). The phenomenon appeared when increasing the rotor speed following a process of ...
    • Herbage, Bernard S. (Texas A&M University. Gas Turbine Laboratories, 1977)
      Fluid film thrust bearings in use on high speed high capacity turbomachinery absorb a great amount of energy in performing their task of positioning rotors. A review of thrust bearing fundamentals along with the latest ...
    • McPherson, Scott; Summa, Calvin (Texas A&M University. Turbomachinery Laboratories, 2009)
      A refining company in the gulf coast had been experiencing accelerated wear on their coke cutting jet pump resulting in major expenditure and down time on a 6-10 month cycle. Application requirements necessitated a pump ...
    • Hirata, Daisuke; Nekomoto, Yoshitsugu; Ibrahim, Fady; Nakaniwa, Akihiro; van Beek, Pieter; Frediani, Luca (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)
      In a centrifugal compressor, interactions between impeller blades and stationary parts such as diffuser vanes will generate high frequency pressure pulsations. The frequencies of these pulsations, so called “blade passing ...
    • Lovelady, Jeff; Bielskus, Pete A. (Texas A&M University. Turbomachinery Laboratories, 1999)
      Oil-free screw (OFS) compressors are capable of producing high-pressure pulsations in the discharge gas stream, over a frequency range of 200 to 3000 Hz. The fundamental pressure pulsation is due to the opening cycle ...
    • Sterns, Dietmar; Elbs, Michael (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
    • Mowrey, Conrad C. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
      Centrifugal pumps that fall into a category defined as high head, low flow pumps are discussed. A brief history of these pump types is presented. The principle of operation and performance envelope are addressed. Comparative ...
    • Taylor, Matthew C.; Vazquez, Jose A. (Texas A&M University. Turbomachinery Laboratories, 2010)
    • Ronan, Josh; Shoup, Thomas; Perney, Gwenael; Robertson, Chad; Quoix, Bernard; Gelin, Alain (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)
      With the increasing demand for high performance gearboxes, larger, faster, more highly loaded bearings are requiring more oil and creating more heat than ever before. This means the lubrication systems must be larger to ...
    • Pennington, Steven; O'Neil, Mark; Sakers, Chuck; Vollmer, Ray (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This course covers the design and application of high performance couplings and rotating machines. Initially the Turbomachinery driver and driven machines are analyzed together with their characteristics and how they affect ...
    • Nirchi, Fernando; Sears, John (Texas A&M University. Turbomachinery Laboratories, 2004)
      Dry gas seal conversions over the last 20 years have progressively become a standard upgrade solution to improving reliability, efficiency, safety and environmental issues related to oil seal technology. The application ...
    • Klostermann, Gregory E. (Texas A&M University. Turbomachinery Laboratories, 1999)
      Since the introduction of noncontacting, gas lubricated, dual pressurized mechanical seals for process pumps over five years ago, and they have primarily been applied to ANSI pumps and other applications where the barrier ...
    • Ohama, Takao; Koga, Takao; Kurioka, Yoshinori (Texas A&M University. Turbomachinery Laboratories, 2004)
      Oil-free screw compressors have been used for process gas application since the 1970s. Oil-flooded screw compressors have been used in many process related applications since the 1980s. Inclusion of oil-flooded screw ...
    • Smith, Alton; Vanhie, Eric (Turbomachinery Laboratory, Texas A&M University, 2011)
