RISEffects of Riblet Dimensions on the Transitional Boundary Layers Over High-Lift Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Substantial research exists in the literature on reducing the profile loss of transitional boundary layers over low-pressure turbine (LPT) blades via different mechanisms such as freestream turbulence, upstream wakes, and ...
Profile Loss Reduction of High-Lift Turbine Blades With Rough and Ribbed Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Transitional boundary layers on low-pressure turbines (LPTs) are prone to separation on the suction surface of the blade under strong local adverse pressure gradients. Intermittent freestream turbulence, periodic wakes ...
