Measurements Concerning the Influence of Surface Roughness and Profile Changes on the Performance of Gas Turbines
(The American Society of Mechanical Engineers (ASME), 1972)During operation the blading of turbines undergoes certain changes. Corrosion, erosion, and contamination cause deterioration of the surface quality and blade profile changes. As a result, the ... -
Heat Transfer Characteristics of a Liquid-Metal Filled Closed Thermosyphon
(The American Society of Mechanical Engineers (ASME), 1972)Experimentally determined heat transfer characteristics are presented for two geometrically similar, closed thermosyphons. Results using water, mercury, and the sodium-potassium eutectic, NaK 56/44, ... -
Axial Flow Compressor and Turbine Loss Coefficients: A Comparison of Several Parameters
(The American Society of Mechanical Engineers (ASME), 1972)Many loss parameters are used in the turbomachinery field for correlating the effects on losses of numerous geometric and aerodynamic variables associated with blade rows. The parameter most ... -
The Use of Cascade Technology in Centrifugal Compressor Vaned Diffuser Design
(The American Society of Mechanical Engineers (ASME), 1972)This paper highlights some results from experience with use of cascade technology in the design of diffusers for centrifugal compressors. The designs consisted of conformally transformed tandem ... -
Powering of Natural Gas Pipelines
(The American Society of Mechanical Engineers (ASME), 1972)An expression is developed for natural gas pipeline flow in terms of station power rather than the usual differences in the squares of the pressures, thus making it possible to directly ... -
Modeling of Gas Turbine Combustors—A Convenient Reaction Rate Equation
(The American Society of Mechanical Engineers (ASME), 1972)In order to model a practical combustion system successfully, it is necessary to develop one or more reaction rate equations which will describe performance over a wide range of conditions. ... -
Proposed Gas Turbine Procurement Standard, Rating and Performance
(The American Society of Mechanical Engineers (ASME), 1972)It has been difficult for users to compare gas turbines produced by different manufacturers due to different approaches used in specifying terms and operating modes. This paper describes standard ... -
Investigation of Air Bearings for Small High-Performance Aircraft Gas Turbines
(The American Society of Mechanical Engineers (ASME), 1972)High temperatures and rotative speeds of future U. S. Army aircraft propulsion systems will impose increasingly severe operating requirements on oil-lubricated engine bearings and associated seals. ... -
Nonlinear Analysis of Rotating Stall
(The American Society of Mechanical Engineers (ASME), 1972)A new stall model to describe rotating stall in axial-flow compressors is established, where blade rows are replaced by semiactuator disks, flow fluctuations are permitted to be finite and ... -
Formation and Control of Oxides of Nitrogen Emissions From Gas Turbine Combustion Systems
(The American Society of Mechanical Engineers (ASME), 1972)Results of an investigation into the levels of oxides of nitrogen in Westinghouse gas turbine exhausts are presented. Various methods of controlling the amounts of these emissions were considered. ... -
