dc.description.abstractThe purpose of this research was to compare numerical predictions with experimental results and to devise an accurate laser anemometry technique to measure in the endwall region of a confined annulus. Flowfield characteristics were computed using a three-dimensional flow solver with the numerical plane coincident with the experimental measurement location. An annular turbine cascade, designed for laser-Doppler velocimetry, was modified to obtain blade passage midspan surface pressure measurements. A range of predicted subsonic and transonic midspan surface pressures were compared favorably with experimental measurements. Two-dimensional Mach number, flow angle, and turbulence intensity measurements were obtained with a fiber-optics laser- Doppler velocimeter. These measurements were performed through a 1.0922 millimeter opening in the endwall at depths ranging from 0.01 mm to 3.34 mm and the results were compared with numerical predictions. (AN)en_US
