Efficiency: The Silent Partner Of Machine Performance
(Texas A&M University. Turbomachinery Laboratories, 1982)
Careful attention is given to the most common, turbomachinery performance problems which result from an inadequate understanding of component and machine efficiency. Examples of several classical problems are presented and ...
Performance Improvements Of A Westinghouse W-171 Gas Turbine By Coating Axial Compressor Blading
(Texas A&M University. Turbomachinery Laboratories, 1982)
Gas turbine performance and efficiency is of increasing interest with the rising cost of energy. The axial compressor of a gas turbine requires 70% of it’s generated horsepower for operation, which makes the compressor an ...
Advanced Technologies For Turbomachinery Systems - An Overview
(Texas A&M University. Turbomachinery Laboratories, 1982)
Any performance gain in a turbomachinery system requires some advancements in a number of technological areas. The components (compressor, combustor, and turbine), materials, structural integrity, lubrication, bearings, ...
New Developments In Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 1982)
Design goals and operating experience with a new bearing design and a new microprocessor based compressor control system are discussed. Both of these developments are included in a compressor designed for the small centrifugal ...
Abradable Seals In Turbomachinery
(Texas A&M University. Turbomachinery Laboratories, 1982)
The intent of this paper is to describe various aspects of the application of abradable seals to industrial turbomachinery. Topics covered include sealing locations, materials, comparative studies and examples of the use ...
Prerotation And Fluid Recirculation In The Suction Pipe Of Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 1982)
Two groups of pumps were investigated in great detail and the analysis showed that large variations in QcR, for the same design specific speed, can be obtained by modifying the design of the rotating channels. An attempt ...
Shop Full-Load Testing Of Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 1982)
The high reliability traditionally required of turbocompressors has become even more imperative in recent years, due to increased unit power and the extreme environmental conditions of many applications. These machines are ...
Inlet Flow And Aspects Of Cavitation In Centrifugal Impellers
(Texas A&M University. Turbomachinery Laboratories, 1982)
This paper describes the relationships of inlet velocity distribution, incipient cavitation and suction performance of centrifugal pumps. It also discusses, in particular, the aspects of cavitation as related to inlet ...
Material Coating By The Detonation Gun Process
(Texas A&M University. Turbomachinery Laboratories, 1982)
There are numerous methods available to repair compressor and turbine shafts when bearing journals, seal surfaces and other critical areas require resurfacing. One of these methods is by the use of detonating gun coatings. ...
Continuous Monitoring Systems For High Speed Gearing
(Texas A&M University. Turbomachinery Laboratories, 1982)
The most effective methods for monitoring the health of high speed gearing is currently generating more interest and discussion than any other aspect of machinery health monitoring. Both structurally and dynamically, a ...
