RISInvestigation of a Novel Secondary Flow Feature in a Turbine Cascade With End Wall Profiling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel secondary flow feature, previously unreported for turbine blading as far as the authors are aware, has been discovered. It has been found that it is possible to separate part of the ...
Separation and Transition Control on an Aft-Loaded Ultra-High-Lift LP Turbine Blade at Low Reynolds Numbers: High-Speed Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the second part of an investigation of the combined effects of unsteadiness and surface roughness on an aft-loaded ultra-high-lift low-pressure turbine (LPT) profile at low ...
Separation and Transition Control on an Aft-Loaded Ultra-High-Lift LP Turbine Blade at Low Reynolds Numbers: Low-Speed Investigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was conducted to improve the performance of an aft-loaded ultra-high-lift low-pressure turbine blade known as U2 at low Reynolds numbers. This was achieved by manipulation ...
The Application of Ultra High Lift Blading in the BR715 LP Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The original LP turbine of the BR715 engine featured “High Lift” blading, which achieved a 20-percent reduction in aerofoil numbers compared to blading with conventional levels of lift, reported ...
