摘要
本文在[3]的基础上,进一步将传统奇点法的应用范围从计算不可压缩流动推广到叶轮机械任意回转面亚音速可压缩流动的计算,并在数值处理方面做了有益的改进.算例和设计实例表明本方法计算可靠并具有实用性,为叶轮机械准三元流动计算中S_1和S_2两类流面间的反复迭代提供了一个有力的计算工具.
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.
