RISTurbine Separation Control Using Pulsed Vortex Generator Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The application of pulsed vortex generator jets to control separation on the suction surface of a low-pressure turbine blade is reported. Blade Reynolds numbers in the experimental, linear turbine ...
The Fluid Dynamics of LPT Blade Separation Control Using Pulsed Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of pulsed vortex generator jets on a naturally separating low-pressure turbine boundary layer have been investigated experimentally. Blade Reynolds numbers in the linear turbine cascade ...
Predicting Separation and Transitional Flow in Turbine Blades at Low Reynolds Numbers—Part II: The Application to a Highly Separated Turbine Blade Cascade Geometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There has been a need for improved prediction methods for low pressure turbine (LPT) blades operating at low Reynolds numbers. This is known to occur when LPT blades are subjugated to high ...
Predicting Separation and Transitional Flow in Turbine Blades at Low Reynolds Numbers—Part I: Development of Prediction Methodology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There is an increasing interest in design methods and performance prediction for aircraft engine turbines operating at low Reynolds numbers. In this regime, boundary layer separation may be more ...
An Investigation of Reynolds Lapse Rate for Highly Loaded Low Pressure Turbine Airfoils With Forward and Aft Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental and computational study of the midspan low Reynolds number loss behavior for two highly loaded low pressure turbine airfoils, designated L2F and L2A, which ...
