Discussion: “Measured Coolant Distributions Downstream of Single and Double Rows of Film Cooling Holes” (Afejuku, W. O., Hay, N., and Lampard, D., 1983, ASME J. Eng. Power, 105, pp. 172–177)
Publisher: The American Society of Mechanical Engineers (ASME)
Full-Coverage Discrete Hole Wall Cooling: Discharge Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Factors influencing the design of full coverage drilled plate wall cooling systems for gas turbine combustors are studied. It is shown that the large number of small diameter holes required ...
The Influence of Premixed Combustion Flame Stabilizer Geometry on Flame Stability and Emissions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Premixed combustion systems for gas turbines offer the possibility of low-pollution, high-combustion efficiency and good temperature distribution. They form a basis by which other well-mixed ...
Full-Coverage Discrete Hole Film Cooling: Investigation of the Effect of Variable Density Ratio
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results of the overall and adiabatic cooling effectiveness for full-coverage discrete hole film cooling are presented for a range of practical geometries. The results are reported ...
Enhanced Impingement Heat Transfer: The Influence of Impingement X/D for Interrupted Rib Obstacles (Rectangular Pin Fins)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impingement flat wall cooling, with 15.2 mm pitch square hole arrays, was investigated in the presence of an array of interrupted rib obstacles. These ribs took the form of rectangular pin-fins ...
Full Coverage Impingement Heat Transfer: Influence of the Number of Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The choice of hole diameter in impingement cooling requires the number of holes to be specified and design information is provided for this purpose. The correlations for impingement cooling ...
Jet Shear Layer Turbulent Diffusion Flames for Ultralow NOx Emissions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Direct fueling of each shear layer generated by an array of holes in a grid plate was shown to have ultralow NOx emissions combined with a good flame stability, compared with a premixed ...
A Computational Study of Pressure Effects on Pollutant Generation in Gas Turbine Combustors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical study of the effect of pressure on the formation of NOx and soot in an axisymmetric 30 deg counterrotating axial swirler lean low-NOx gas turbine combustor has been conducted. ...
Small Diameter Film Cooling Holes: Wall Convective Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wall heat transfer resulting from small diameter holes drilled at 90 deg through gas turbine combustion chamber and turbine blade walls is considered. Available information is briefly reviewed ...
Impingement/Effusion Cooling: The Influence of the Number of Impingement Holes and Pressure Loss on the Heat Transfer Coefficient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measurements of the overall heat transfer coefficient within an impingement/effusion cooled wall are presented. The FLUENT CFD computer code has been applied to the internal aerodynamics to ...
