RISEffect of Blade Profile Contouring on Endwall Flow Structure in a High-Lift Low-Pressure Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous work has shown that low-stagger contouring near the endwall of a nominally high-lift and high-stagger angle front-loaded low-pressure turbine (LPT) airfoil is successful in reducing endwall loss by limiting the ...
Entry Region Heat Transfer Augmentation With Pins, Fins, and Turbulators in Circular Channels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Entry region heat transfer is known to provide significantly higher heat transfer than fully developed conditions. Utilizing entry region heat transfer would provide an additional heat sink at the inlet of an aircraft ...
Endwall Loss Reduction of High Lift Low Pressure Turbine Airfoils Using Profile Contouring—Part I: Airfoil Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the reasoning for and the design process of contouring a high lift frontloaded low pressure turbine (LPT) airfoil near the endwall to reduce the endwall loss. The test airfoil, L2F, was designed to the ...
