(Texas A&M University. Turbomachinery Laboratories, 2002)The ongoing trend toward automation of the oil, gas, and chemical industry has significantly changed the entire industry. Digital control systems utilizing advanced computer technologies are installed to manage integrated ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)Although turbocompressors have been designed, built, and used in increasingly stringent conditions for more than 80 years, the turbomachinery industry, like all comparable industries, can only design and manufacture its ...
-
(Turbomachinery Laboratory, Texas A&M University, 2010)Wear erosion needs special attention in pump design as it can lead to severe damage of the pump and restrict its lifetime significantly. It therefore determines to a large extent the selection of a pump. During the design ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)During full load testing of moto-compressor, abnormal vibration were detected. Failure was observed on electrical motor rotor lamination teeth. Deep experimental analysis and metallurgical investigations revealed a high ...

(Texas A&M University. Turbomachinery Laboratories, 2012)The two main refrigeration compressor strings at Tangguh LNG are highly dependent on each other during operation: A cascading trip can happen within seconds. This case study focuses on how to keep either string online when ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)Pump reliability problems are responsible for a large amount of the maintenance budget and lost-opportunity cost at chemical plants, refineries, and many electric utilities. This tutorial outlines the typical reasons for ...
-
(Texas A&M University. Turbomachinery Laboratories, 1992)Axial air compressors have seen increased service in various applications over the years, mainly because of the axial compressor's high operating efficiency, which can be 85 to 90 plus percent. The design of the aerodynamic ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)Turbomachinery shafting and casings typically experience axial growth during thermal transients occurring at startup, shutdown, and changes of load. This growth does not usually present difficulties during operation. ...
-
(Texas A&M University. Turbomachinery Laboratories, 2006)Gas turbine performance deterioration can be a major economic factor. An example is within offshore installations where a degradation of gas turbine performance can mean a reduction of oil and gas production. This paper ...
-
(Texas A&M University. Turbomachinery Laboratories, 2014)Severe axial subsynchronous vibrations (SSV) can be encountered in turbomachinery. A major concern is the potential for danger from the high levels of vibration acting on the rotor. Longer term implications are fretting ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)The residual axial thrust acting on the rotor of a centrifugal compressor is the result of the non-uniform pressure distribution on the surfaces in contact with the process gas, plus the differential pressure acting on the ...
-
(Texas A&M University. Gas Turbine Laboratories, 1976)Increased usage of metal-flexing couplings on high-speed rotating machinery has created awareness of the axial resonant vibration characteristics of this type of coupling. A testing program has been conducted at Rexnord ...
