Abstract
PURPOSE: To reduce the inlet loss and increase the efficiency by continuously varying the inlet vane angle of a diffuser to the direction of the vane width and forming a smooth curveture with the crosssectional center line looking from the axial direction.
CONSTITUTION: The vane angle at the inlet of the side plate side centerline 4c is made small and the vane angle at the inlet of middle center line 4b is made large while the vane angle at the inlet of the center plate side center line 4a is made slightly small. The foregoing inlet vane angle distribution matches the twisted speed distribution at the outlet of the impeller whereby the inlet loss is reduced.
