Loss Measurements in the Endwall Region of a Cascade of Compressor Blades at Stall

Abstract

Flow around second-generation controlled-diffusion blades in cascade at stall was investigated using five-hole probe surveys. Wake pressure surveys were conducted at various locations between the cascade centerline and endwall region. Corresponding inlet pressure surveys were also performed to allow the total pressure loss distribution to be calculated across the blades. A fully automated traverse mechanism was implemented for the probe surveys ahead of and aft of the cascade blades. The number of wake surveys conducted allowed the pressure distribution profiles to show pressure deficiencies at the endwall region in greater detail than previous studies.
