Definition of a Screening Criterion for Centrifugal Compressor Vibrations Induced by Inlet Gas Flow
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 4: The gas flow entering from the inlet flange of a centrifugal compressor may induce radial forces on the rotor, by directly impinging onto shaft or by generating asymmetric pressure fluctuations in the gas volume ...
Experimental Evaluation of the Effectiveness of Online Water-Washing in Gas Turbine Compressors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 7: An investigation of the effectiveness of online combustion turbine axial compressor washing using various purity grade waters and commercial washing detergents was performed. For this project, blade surface ...
Gas Turbine Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Tutorial 1: The power and efficiency characteristics of a gas turbine are the result of a complex interaction of different turbo machines and a combustion system. In this tutorial, we will address the basic characteristics ...
LNG Liquefaction Plants - Overview, Design & Operations: Short Course
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Full Speed String Test On LM6000PF Gas Turbine Driven Refrigeration Compressors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Chevron Australia, as part of the Wheatstone Project, constructed a two train liquefied natural gas (LNG) facility and domestic gas plant at the Ashburton North Strategic Industrial Area, 12 kilometers west of Onslow on ...
Aero-Damping Measurements And Computation In A Full-Scale Multistage Centrifugal Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Great interest is being paid by Oil & Gas industry to the design of high speed and high pressure ratio centrifugal compressors. Static and dynamic stresses are becoming higher and, under critical conditions, aerodynamic ...
Impeller Stall Induced By Reverse Propagation Of Non-Uniform Flow Generated At Return Channel
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
In the case of centrifugal compressors, minor non-uniform flow upstream of the impeller is induced by an asymmetrical configuration in the circumferential direction at the compressor suction casing. This non-uniform flow ...
A Review Of Aerodynamically Induced Forces Acting On Centrifugal Compressors, And Resulting Vibration Characteristics Of Rotors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
There are several sources of non-synchronous forced vibration of centrifugal compressor rotors. Many of them are aerodynamic phenomena, created within the gas path of the compressor. Phenomena such as impeller stall, ...
Redesign of Centrifugal Compressor Impeller by means of Scalloping
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Impellers of centrifugal compressors may experience resonance with vane passing frequencies, especially when operated away from the design conditions. Resonance can cause a serious structural damage to impeller. Complete ...
Asynchronous Motor - Failure of Rotor Lamination Teeth
(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 ...
