Effects of Trailing Edge Thickness and Blade Loading Distribution on the Aerodynamic Performance of Simulated CMC Turbine Blades

Autor: John P. Clark, Vikram Shyam, Paul W. Giel, Paht Juangphanich

Publikováno v: Volume 2B: Turbomachinery.

The aerodynamic performance of three blade sets that represent the geometric manufacturing constraints of Ceramic Matrix Composite (CMC) blades was measured experimentally in a large-scale transonic turbine blade cascade. The trailing edge thicknesse

Transonic turbine blade loading calculations using different turbulence models – effects of reflecting and non-reflecting boundary conditions

Autor: Paul W. Giel, S. Djouimaa, L. Messaoudi

Publikováno v: Applied Thermal Engineering. 27:779-787

The objective of this study is to simulate the transonic gas turbine blade-to-blade compressible fluid flow. We are interested mainly in the determination of the pressure distribution around the blade. The particular blade architecture makes these si

Aerodynamic Effects of High Turbulence Intensity on a Variable-Speed Power-Turbine Blade with Large Incidence and Reynolds Number Variations

Autor: Paul W. Giel, Gerard E. Welch, Ashlie B. Flegel

Publikováno v: 50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference.

The effects of high inlet turbulence intensity on the aerodynamic performance of a variable speed power turbine blade are examined over large incidence and Reynolds number ranges. These results are compared to previous measurements made in a low turb

Inlet Turbulence and Length Scale Measurements in a Large Scale Transonic Turbine Cascade

Autor: Doug Thurman, Ashlie B. Flegel, Paul W. Giel

Publikováno v: 50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference.

Constant temperature hotwire anemometry data were acquired to determine the inlet turbulence conditions of a transonic turbine blade linear cascade. Flow conditions and angles were investigated that corresponded to the take-off and cruise conditions

Simulation of VSPT Experimental Cascade under High and Low Free-Stream Turbulence Conditions

Autor: Paul W. Giel, Ashlie B. Flegel, Ali Ameri

Publikováno v: 50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference.

Variable-Speed Power Turbines (VSPT) for rotorcraft applications operate at low Reynolds number and over a wide range in incidence associated with shaft speed change. A comprehensive linear cascade data set obtained includes the effects of Reynolds n

Aerodynamic Measurements of a Variable-Speed Power-Turbine Blade Section in a Transonic Turbine Cascade at Low Inlet Turbulence

Autor: Paul W. Giel, Gerard E. Welch, Ashlie B. McVetta

Publikováno v: Volume 6A: Turbomachinery.

Aerodynamic measurements obtained in a transonic linear cascade were used to assess the impact of large incidence angle and Reynolds number variations on the 3-D flow field and midspan loss and turning of a 2-D section of a variable-speed power-turbi

Validation of a CFD Methodology for Variable Speed Power Turbine Relevant Conditions

Autor: Ali Ameri, Paul W. Giel, Ashlie B. McVetta

Publikováno v: Volume 6B: Turbomachinery.

Analysis tools are needed to investigate aerodynamic performance of Variable-Speed Power Turbines (VSPT) for rotorcraft applications. The VSPT operates at low Reynolds numbers (transitional flow) and over a wide range of incidence. Previously, the ca
