| Abstract: | Traditional singularity method can be only used to catculate incompressible flow, but in this paper it is extended to calculate subsonic compressible flow on an arbitrary stream surface of turbomachinery. And some beneficial modifications are also made in numerical technique. Numerical and design examples show that this method is reliable and practical, and it is also suitable and efficient for repeated calculations between the S_1 and S_2 stream surfaces in the quasi three dimensional solution of turbomachinery. |
