Investigation of the Unsteady Pressure Distribution on the Blades of an Axial Flow Fan.

Abstract

The results of a program to investigate the distribution of unsteady pressure on the blades of a stator blade row in an axial flow turbomachine which operated in the wakes of an upstream rotor are presented. These unsteady pressure distributions were measured using a blade instrumented with a series of miniature pressure transducers which was developed in this program. Several geometrical and flow parameters--rotor/stator spacing, stator solidity, and stator incidence angle--were varied to determine the influence of these parameters on the unsteady response of the stator.
