Abstract

Abstract

The static pressure distributions on endwalls and blade surfaces and the corresponding outlet flow for straight、leaned and curved blades of plane axial compressor cascades at 0° incidence were measured in detail.The experimental results show that C-shape static pressure distribution can be obtained on the blade surface of the curved blades along blade height.Blade leaning and curving can eliminate piling up of low energy fluid in the blade corner,cut down the endwall losses,retard corner stalling,and improve cascade aerodynamic characteristics.
