RISEndwall Loss and Mixing Analysis of a High Lift Low Pressure Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high lift low pressure turbine (LPT) profile designated L2A is used as a test bed for studying the origin of endwall mixing loss and the role of vortical structures in loss development. It is shown analytically and ...
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 ...
