Discussion: “Unsteady Interaction Effects on a Transitional Turbine Blade Boundary Layer” (Ashworth, D. A., LaGraff, J. E., and Schultz, D. L., 1989, ASME J. Turbomach., 111, pp. 162–168)
Publisher: The American Society of Mechanical Engineers (ASME)
Unsteady Conjugate Heat Transfer Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The primary requirement for high pressure turbine heat transfer designs is to predict blade metal temperature. There has been a considerable recent effort in developing coupled fluid convection ...
New Heat Transfer Gages for Use on Multilayered Substrates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes a technique which enables measurements of the surface heat transfer rate to be made using thin-film gages deposited on a vitreous enamel-coated metal model. It is intended ...
Effect of Free-Stream Turbulence on Flat-Plate Heat Flux Signals: Spectra and Eddy Transport Velocities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study of the eddy structure in a flat-plate turbulent boundary layer with significant levels of free-stream turbulence is presented. This is relevant to the enhancement of ...
Simulation of the Effects of Shock Wave Passing on a Turbine Rotor Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unsteady effects of shock waves and wakes shed by the nozzle guide vane row on the flow over a downstream turbine rotor have been simulated in a transient cascade tunnel. At conditions ...
Detailed Boundary Layer Measurements on a Transonic Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The boundary layers of a transonic turbine blade have been measured in detail. The full velocity profiles have been measured at a number of stations on both the suction and pressure surfaces, ...
Large-Scale Testing to Validate the Influence of External Crossflow on the Discharge Coefficients of Film Cooling Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses large-scale, low-speed experiments that explain unexpected flow-interaction phenomena witnessed during annular cascade studies into the influence of external crossflow on film ...
A Method for Correlating the Influence of External Crossflow on the Discharge Coefficients of Film Cooling Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An empirical means of predicting the discharge coefficients of film cooling holes in an operating engine has been developed. The method quantifies the influence of the major dimensionless ...
PIV Maps of Tip Leakage and Secondary Flow Fields on a Low-Speed Turbine Blade Cascade With Moving End Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: New, detailed flow field measurements are presented for a very large low-speed cascade representative of a high-pressure turbine rotor blade with turning of 110deg and blade chord of 1.0m. Data ...
Transonic Turbine Blade Tip Aerothermal Performance With Different Tip Gaps—Part I: Tip Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A closely combined experimental and computational fluid dynamics (CFD) study on a transonic blade tip aerothermal performance at engine representative Mach and Reynolds numbers (Mexit=1,Reexit=1.2 ...
