RISExperimental 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 ...
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 ...
