(Texas A&M University. Turbomachinery Laboratories, 2010)
-
(Texas A&M University. Turbomachinery Laboratories, 2013)
-
(Texas A&M University. Turbomachinery Laboratories, 2004)Cavitation occurring in high-energy pump impellers often results in material erosion and system instabilities. Excessive erosion rates compromise life and increase ownership costs through higher maintenance and reduced ...
-
(Texas A&M University. Turbomachinery Laboratories, 2011)The application of oil-free-integrated motor-compressors has become increasingly popular in recent years. One of the significant features of this class of machinery is compactness, providing space-savings compared to ...
-
(Texas A&M University. Turbomachinery Laboratories, 1995)A critical multistage steam turbine in a large chemical plant experienced high vibration levels and frequent repairs. Numerous failures occurred while passing through the rotor's first critical speed including heavy rubs. ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)Since the release of dual gas lubricated seal technology for process pumps over three years ago, this technology has provided a more versatile, efficient, safe, and less costly alternative to sealless pumps and traditional ...
-
(Texas A&M University. Gas Turbine Laboratories, 1975)This study investigates the steady-state and transient response of the squeeze film damper bearing. Both the steady-state and transient equations for the hydrodynamic bearing forces are derived. The steady-state equations ...
-
(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 ...
-
(Texas A&M University. Turbomachinery Laboratories, 1983)High-speed gears of very high powers and/or very high speeds must be exactly analyzed and optimized in gearing, bearing and housing in order to achieve low noise, low vibration running with maximum safety in operation. The ...
-
(Texas A&M University. Gas Turbine Laboratories, 1975)A description of the application of advanced technology, high temperature, gas turbine design technique to a new model two-shaft type gas turbine to achieve a high efficiency, high reliability, regen cycle and simple cycle ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)A submerged electric (SE) pump has been designed and analyzed for high flow applications. The challenges when designing a high power density SE pump are torsional and lateral dynamics and hydraulic stability. The case ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)Gas lubricated double seals are becoming more common in industry for pump applications where product emission, product contamination, and operating costs are a concern. Technology proven on large gas compressors is not ...
-
(Texas A&M University. Turbomachinery Laboratories, 2000)In the Northern Netherlands, after more than 30 years of production, the pressure of the gigantic Groningen onshore gas field is gradually decreasing, requiring up to 500 MW compression over the next 30 years to fulfil ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)This paper reexamines some of the usual assumptions in deploying synchronous machines in multi-megawatt, high-speed application. The detailed design and experimental evaluation of a prototype high-speed, directly-coupled, ...
-
(Texas A&M University. Gas Turbine Laboratories, 1979)This paper discusses the design of a high pressure reinjection centrifugal compressor. This compressor was tested in the manufacturer’s shop under full load to simulate the field operating conditions in terms of inlet/discharge ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)A mechanical seal improvement program was initiated at a major oil refinery. The program was intended to improve seal reliability, reduce emissions, improve safety, and reduce costs. A partnership agreement was reached ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)A compressor in a natural gas gathering service experienced multiple seal failures on the discharge end. Synthetic oil mist contained in the sealing gas was identified as a significant source of contamination that caused ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)A major producer of ethylene installed and is successfully operating a nonpressurized dual gas seal in liquid methane service. The least reliable pump in the unit was a single stage overhung centrifugal pump in demethanizer ...
