Two dimensional method of flow analysis by the singularity method is proposed to clarify the interactions between a spiral casing and guide vanes. Simultaneous integral equation s of Fredholms type of the 1st kind are solved numerically by applying the spline fitting method to the vortex and source distributions on each element of the spiral casing and also expressing the vortex and source distributions on the camber line of the guide vane by mode functions. The pressure distributions on the spiral casing and guide vane are easily obtained form these singularity distributions and then the mutual interactions between them are clarified in detail. Further comparisons with available experimental data are made to confirm the present method .
