Turbine Vane Endwall Film Cooling Effectiveness of Different Purge Slot Configurations in a Linear Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study is concerned with the film cooling effectiveness of the flow issuing from the gap between the nozzle guide vane (NGV) and the transition duct on the NGV endwall, i.e., the purge slot. Different slot widths, ...
Experimental Study of Endwall Film Cooling and Heat Transfer for Different Upstream Slot and Hole Geometries in an Annular Sector Cascade Under High-Speed and Low-Speed Conditions—Part I: Film Cooling Effectiveness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Endwall film cooling in dry-low emission (DLE) gas turbines is crucial due to increased thermal loads from flat temperature profiles. Cooling strategies typically employ discrete holes or utilize purge air that ...
Experimental Study of Endwall Film Cooling and Heat Transfer for Different Upstream Slot and Hole Geometries in an Annular Sector Cascade Under High-Speed and Low-Speed Conditions—Part II: Heat Transfer and Aerodynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Endwall film cooling strategies typically involve the employment of discrete holes or harness purge air that exits from the gaps between adjacent turbine components. Whichever the technique, the propagation of ...
Impact of Internal Crossflow on Flow Topology Inside and Outside of Film-Cooling Holes With Varying Inclination and Supply Flow Angles: 3D Velocity Data From Magnetic Resonance Velocimetry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Crossflow on both sides of film-cooling holes with engine-representative length-to-diameter ratios significantly impacts flow topology and cooling effectiveness in gas turbine airfoils. This experimental study ...
Heat Transfer in a Rotating, BladeShaped, TwoPass Cooling Channel With Various 45Deg Rib Turbulators and a Tip Turning Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work experimentally studied a rotating, bladeshaped, twopass cooling channel with various 45deg rib turbulators and a tipturning vane. The first passage of the cooling channel has an aspect ratio (AR) = 4:1 with the ...
Comparison of Film Cooling Performance for Different Purge Slot Configurations in a Cylindrical and State-of-the-Art Nozzle Guide Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This comparative study is concerned with the advances in nozzle guide vane (NGV) design developments and their influence on endwall film cooling performance by injecting coolant through the purge slot. This experimental ...
Effect of 45-deg Rib Orientations on Heat Transfer in a Rotating Two-Pass Channel With Aspect Ratio from 4:1 to 2:1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The internal cooling passages of gas turbine blades mostly have varying aspect ratios from one passage to another. However, there are limited data available in the open literature that used a reduced cross section and ...
Development of a Modified RANS-Turbulence Model for the Computational Investigation of Film Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The thermal load on the endwalls of the hot gas path of gas turbines, in particular those of the nozzle guide vanes (NGVs), has increased considerably over the last few decades, both because of the common premixed ...
Experimental Investigation of Turbulence Inside an Annular Turbine Exit Guide Vane Cascade With Unsteady Wakes and Purged Cavity Using Constant Temperature Anemometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The total efficiency of jet engines can be increased by implementing recuperative systems. These systems need an increased fluid total temperature downstream of the low-pressure turbine (LPT). Thus, a method is ...
