Description: The purpose of this research was to compare previous laser anemometry measurements obtained through an unpressurized laser window with the results from a pressurized laser window and to validate this innovative measuring technique in the endwall region of a confined annulus. Two dimensional velocity, flow angle, and turbulence intensity measurements were obtained with a fiber optics laser Doppler velocimeter. The measurements were performed through a 1.09 mm opening in the endwall region of an annular turbine cascade at depths ranging from 0.01 mm to 0.89 mm with varying pressure applied to the chamber of the modified window. Cobra probe measurements were performed to validate the flow angles obtained by the laser anemometer. The cascade was modified to measure the inlet profile, which was performed with a three-hole probe.
