-
(Texas A&M University. Turbomachinery Laboratories, 1994)Predicting potential problems that will ultimately lead to premature material related failures and implementing the necessary corrections during design, fabrication, and commissioning has long been recognized by some as ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)In large diameter piping, high-frequency energy can produce excessive noise and vibration, and failures of thermowells, instrumentation, and attached small-bore piping. In severe cases, the pipe itself can fracture. Perhaps ...
-
(Texas A&M University. Gas Turbine Laboratories, 1974)A recent study of Exxon Corporation's world-wide machinery startups indicated that special purpose gear problems have not been critical in terms of project delays. However, the incidence rate of gear problems has been ...
-
(Texas A&M University. Turbomachinery Laboratories, 1992)The data required by turbine vendors to properly develop a design for a special purpose steam turbine are discussed in detail. Topics covered include discussion of continuous steam conditions, turbine power ratings and ...
-
(Texas A&M University. Turbomachinery Laboratories, 1991)The state-of-the-art magnetic bearing system, as it exists today, has several unique characteristics which tend to make certain applications of this technology more favorable than others. One application which seems quite ...

(Texas A&M University. Turbomachinery Laboratories, 2011)
-
(Texas A&M University. Turbomachinery Laboratories, 1996)Higher speeds, longer shafts, and increased power has made squeeze film damper (SFD) bearing performance increasingly more important to control both synchronous and subsynchronous fibration in rotating machinery. SFD bearing ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Squeeze Film Dampers (SFDs) are effective means to ameliorate rotor vibration amplitudes and to suppress instabilities in rotor-bearing systems. A SFD is not an off-the-shelf mechanical element but tailored to a particular ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)Minimizing fluid induced forces through the secondary leakage flow paths in shrouded centrifugal impellers is crucial to improve the rotordynamic stability of high-pressure centrifugal gas compressors. Swirl brakes (SBs) ...
-
(Texas A&M University. Turbomachinery Laboratories, 2011)In many cases it is necessary to judge the stability behavior of a specific compressor. This might be the OEM checking the feasibility of a proposed compressor layout or it might be the user judging one of his machines ...
-
(Texas A&M University. Turbomachinery Laboratories, 2014)This paper presents results from stability analysis and testing on high pressure CO2 centrifugal compressors, beginning by a preliminary analysis conducted on an academic institution. It includes results of stability tests ...
-
(Texas A&M University. Turbomachinery Laboratories, 1981)An extensive introduction to stall, stage stall and surge is given with examples of the various stall phenomena including recirculation. Particular components including the inducer, impeller, vaneless diffuser, channel ...
-
(Texas A&M University. Turbomachinery Laboratories, 1991)For more than 40 years, integrally geared centrifugal compressors have been in use worldwide, in the plant air sector first, and increasingly in the process industry. Apart from reliability, efficiency and operating range, ...
-
(Texas A&M University. Turbomachinery Laboratories, 1998)The purpose of this paper is to describe how computer simulation was used to size the main starter motors for single shaft gas turbine driven compressor strings used in a large LNG plant. The paper describes how the ...
-
(Texas A&M University. Turbomachinery Laboratories, 1985)The startup of a reliable compressor train involves not only the design and design audit, but also startup testing to verify the functionality of the design. Startup testing usually includes mechanical and electrical system ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)
-
(Texas A&M University. Gas Turbine Laboratories, 1978)Advances in 3-D finite element stress analysis, as well as powerful analytical technique in rotor dynamics and bearing analysis using high speed digital computers, have created the environment to build process centrifugal ...
-
(Texas A&M University. Turbomachinery Laboratories, 2012)Predicting the performance of directly lubricated bearings is a challenge facing bearing manufacturers and end users alike. In this study, thermoelastohydrodynamic (TEHD) theories are applied to analyze three directly ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)It is shown as the outline in this short course that the role of steam turbine, history, classification, basic structure, components and their function, manufacturing and design process and control system. And also, the ...
