• The flow behaviours of the flow field in a impeller and guide vane of axial blower have been observed using the technique of visualization by silk tufts. When the stall zone is limited to the tip region only, the surging zone on the ψ-φ characteristics does not appear clearly. Therefore, if the suction or delivery concentric rings have the effect to prevent the stall zone from extending toward the section within geometrical mean radius, the stall characteristics of an axial machine will be improved. In the stationary guide vane of an axial blower, the blade characteristics are better than those of other section, owing to the flow in the boundary layer from tip to root caused by a secondary flow in the curved channel.
