dc.description.abstractA fundamental investigation of the flow in the endwall corner region of a linear compressor cascade wind tunnel and the effect of boundary layer blowing in this region was conducted using blade surface pressure tap measurements and five - hole prism probe measurements taken downstream of the cascade. The results are presented as a series of velocity vector plots, loss contour plots, and pitchwise mass - averaged loss coefficient plots. The angle of attack test range was from 5 to 29 degrees. For the corner region boundary layer blowing investigations, two slots were machined into the ends of a set of cascade blades, and an external air source was used as the blade slot jet air source. Tests were done for 19, 21, and 23 degrees angle of attack. The main effect of corner boundary layer blowing was a significant reduction in total pressure losses in the region along the blade span between the exterior portion of the corner boundary layer flow and the blade profile boundary layer flow.en
