Boyce, Meherwan P.; Trevillion, William L.; Brown, Michael L. (Texas A&M University. Gas Turbine Laboratories, 1976)The objective of this paper is to acquaint the reader with the developments in the field of turbomachinery. The research conducted at the Gas Turbine Laboratories has two primary goals. First, to improve the efficiency of ...

Landon, Fred K.; Counter, Louis F. (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 ...
-
Gunter, E. J.; Barrett, L. E.; Allaire, P. E. (Texas A&M University. Gas Turbine Laboratories, 1976)In this paper, we will consider only the problem of synchronous rotor response due to unbalance. There are numerous complex nonsynchronous vibrations that can occur in rotating machinery. Quite often the nonsynchronous ...
-
Gibbons, C. B. (Texas A&M University. Gas Turbine Laboratories, 1976)Misalignment of machinery shafts causes reaction forces to be generated in the coupling which affect the machines and are often a major cause of machinery vibration. The reaction forces generated by the couplings are ...
-
Van Laningham, Fred L. (Texas A&M University. Gas Turbine Laboratories, 1976)Gear case distortion due to thermal effects has caused unique and costly failures at several of Union Carbide's process plants. The unusual nature of these failures has prompted us to make an in-depth logical investigation ...
-
Brown, John A. (Texas A&M University. Gas Turbine Laboratories, 1976)With cost of energy in the $2.00 per 10^6 BTU range throughout the Western Industrialized World, the current value of one horsepower over a five-year period is in excess of $600. This high energy valuation is of relatively ...

Boyce, Meherwan P.; Bayley, Richard D.; Sudhaker, Vankayalapati; Elchuri, Vijayvardhan (Texas A&M University. Gas Turbine Laboratories, 1976)An accurate evaluation of the performance of a dynamic rotary compressor is of paramount interest to the builder and user of this type of machinery because it defines the ability of a machine to perform a specific job and ...
-
Wickl, R. (Texas A&M University. Gas Turbine Laboratories, 1976)Owing to high fuel costs, European Companies have always had to use special care in planning their process-energy requirements. Therefore, the industrial steam turbine has also played a major part in this respect. The ...
-
Massey, John R. (Texas A&M University. Gas Turbine Laboratories, 1976)The profitability, reliability and maintenance of gas turbine driven centrifugal compressor units are not inherent with the machinery, but for the most part, depend on the piping system to which they are connected and the ...
-
Geiser, Kenneth W. (Texas A&M University. Gas Turbine Laboratories, 1976)Centrifugal compressors have been used to compress oxygen for at least 25 years. Until ten years ago, the flows were relatively small and discharge pressures were relatively low. In the mid 1960's the size of single train ...
-
Calistrat, M. M. (Texas A&M University. Gas Turbine Laboratories, 1976)The performance of a Metal Diaphragm Coupling is to a large extent determined by its endurance limit. The endurance limit can be estimated by calculations but must be confirmed through testing. The author cites data obtained ...
-
Spechtenhauser, Alfred M. (Texas A&M University. Gas Turbine Laboratories, 1976)Following a review of possible alternative solutions regarding the choice of a mechanical driver; i.e., electric motor, gas turbine or steam turbine, it is demonstrated that the steam turbine as applied in industry is ...
-
Makay, Elemer (Texas A&M University. Gas Turbine Laboratories, 1976)Although mechanical and hydraulic instabilities in centrifugal pumps caused a considerable amount of problems for large Nuclear and Fossil Generating Stations influencing "Power Plant Availability," a relatively limited ...
-
Sparks, Cecil R.; Wachel, J. C. (Texas A&M University. Gas Turbine Laboratories, 1976)The existence of high intensity, low frequency pulsation problems in centrifugal compressor and pump piping systems has now been well documented throughout industry. Strong pulsations have been observed at frequencies ...
-
Weaver, Firm L. (Texas A&M University. Gas Turbine Laboratories, 1976)The paper discusses the fundamental relationships between turbine overspeed and the time constant of the rotor. The amount of overspeed is shown to be related not only to the time lag of the emergency tripping devices, but ...
-
Maxwell, A. S.; Sanderson, A. F. P. (Texas A&M University. Gas Turbine Laboratories, 1976)When turbine-generators operating at constant speed require site trim balancing, this is most commonly performed at the synchronous speed using a conventional influence coefficient method. In some cases, the vibration of ...

Diehl, George M. (Texas A&M University. Gas Turbine Laboratories, 1976)An expression of the noise rating of a machine is an important part of its performance specification. Precautions should be taken, however, to make sure that the noise emission specification keeps the true objective in ...
