The paper presents the results of a theoretical and experimental investigation into the potential flow interaction effects between blade rows in an axial flow compressor stage. The investigation is concentrated on the inlet guide vane/rotor interaction and shows that the passing of the rotor blades behind the guide vanes produces large pressure fluctuations on the surfaces of the guide vanes.
The available method of computation is not yet adequate for prediction of absolute values of pressure amplitude but does provide a sound basis for comparison between alternative designs.
