Abstract: In the design of the quasi three dimensional of S 2 stream surface in compressors,three calculation methods namely the flow function method,the streamline curvature solution method and the Euler method have been adopted widely.In terms of the system of equation and the method of calculation,these methods were compared with each other and with the result of a three stage axial flow compressor.At last,six related conclusions were drawn.At pressent,there are not enough data to show which method is better.It was suggested that these methods should be used properly in terms of the basic contradiction in design.
