| Abstract: | The effects of normal straight, leaned and curved blade of plane axial flow compressor cascades were investigated. Detailed measurements of the outlet flow fields of these three cascades have been carried out at 0 incidence. Through the analyses and comparisons of the experimental results, and combined with the surface flow visualizations and the static pressure distributions of the endwalls and blade surfaces, the improvements of blade leaning and curving on the outlet flow fields are discussed herein. It is found that blade leaning and curving can eliminate the piling up of low energy fluids in blade corner (near suction surface),reduce the endwall losses and postpone corner stalling and improve cascade aerodynamic characteristics. |
