RISFundamental Gas Turbine Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas turbines are used for aircraft propulsion and landbased power generation or industrial applications. Thermal efficiency and power output of gas turbines increase with increasing turbine rotor inlet temperatures (RIT). ...
Identification of Acoustic Characteristics of Honeycomb Sandwich Composite Panels Using Hybrid Analytical/Finite Element Method1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the purpose of identifying the acoustic characteristics of honeycomb sandwich panels, finite element method (FEM), combined with boundary element method (BEM), has been widely used. However, the latter approach is not ...
Advanced Cooling in Gas Turbines 2016 Max Jakob Memorial Award Paper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas turbines have been extensively used for aircraft engine propulsion, land-based power generation, and industrial applications. Power output and thermal efficiency of gas turbines increase with increasing turbine rotor ...
Swirl Impinging Cooling on an Airfoil Leading Edge Model at Large Reynolds Number
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Jet impingement cooling has been extensively investigated due to its significant applications on the airfoil leading edge region; however, most of which are about normal jet impingement. The systematic research on swirl ...
Effect of Coolant Density on Leading Edge Showerhead Film Cooling Using the Pressure Sensitive Paint Measurement Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The density ratio effect on leading edge showerhead film cooling has been studied experimentally using the pressure sensitive paint (PSP) mass transfer analogy method. The leading edge model is a blunt body with a semicylinder ...
Impingement Heat Transfer From Jet Arrays on Turbulated Target Walls at Large Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments to investigate heat transfer and pressure loss from jet array impingement are performed on the target wall at high Reynolds numbers. Reynolds numbers up to 450,000 are tested. The presence of a turbulated target ...
Influence of Coolant Density on Turbine Platform Film Cooling With Stator–Rotor Purge Flow and Compound Angle Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A detailed parametric study of filmcooling effectiveness was carried out on a turbine blade platform. The platform was cooled by purge flow from a simulated stator–rotor seal combined with discrete hole filmcooling. The ...
Heat Transfer and Pressure Loss Measurements in a Turbulated High Aspect Ratio Channel With Large Reynolds Number Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments to investigate heat transfer and pressure loss are performed in a rectangular channel with an aspect ratio of 6 at very high Reynolds numbers under compressible flow conditions. Reynolds numbers up to 1.3 أ— 106 ...
Influence of Coolant Density on Turbine Blade Film Cooling With Axial and Compound Shaped Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Adiabatic filmcooling effectiveness is examined systematically on a typical high pressure turbine blade by varying three critical flow parameters: coolant blowing ratio, coolanttomainstream density ratio, and freestream ...
Heat Transfer and Pressure Loss in a Two-Pass, Rectangular Channel Featuring a Reduced Cross-Sectional Area After the 180-Deg Tip Turn With Different Turning Vane Configurations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Serpentine, multi-pass cooling passages are used in cooling advanced gas turbine blades. In the open literature, most internal cooling studies use a fixed cross-sectional area for multi-pass channels. Studies that use ...
