Transient Analyses Of Synchronous Motor Trains
(Texas A&M University. Gas Turbine Laboratories, 1978)
This paper discusses the philosophy of optimum location of torsional critical speeds which will be excited by the transient startup, as well as methods of adjusting the resonant frequencies. Pulsating torque, average torque, ...
Dynamic Characteristics Of Fluid-Film Bearings
(Texas A&M University. Gas Turbine Laboratories, 1977)
The concept of cross-coupling in bearings is introduced and its influence on bearing dynamics is presented. Procedures for obtaining cross-coupled spring and damping coefficients are explained. The special case of pad pitch ...
The Design Of Support Structures For Elevated Centrifugal Machinery
(Texas A&M University. Gas Turbine Laboratories, 1977)
This paper briefly discusses the computer aided analysis and design of elevated turbomachinery support structures. The paper is focused upon structural behavior and is presented from the civil engineer's viewpoint. The ...
Centrifugal And Axial Flow Fan Applications And Design Criteria
(Texas A&M University. Gas Turbine Laboratories, 1977)
The application of fan equipment covers a wide range in today's market and requires that attention be given to factors which were not a consideration in the past. The high costs of energy, installation, replacement parts, ...
Evaluation Of Liquid Film Seals, Associated Systems And Process Considerations
(Texas A&M University. Gas Turbine Laboratories, 1977)
Buffered bushing liquid-film seals have been in existence for some time and have proven to be quite reliable for most centrifugal compressor applications. However, industry has been demanding more from seals and their ...
