本文从扰动在叶轮机流场中传播的分析进一步阐明了两类计算问题常规算法都可以得到M_m<1.0而M_m>1.0的超音速解,并给出了轴流压气机级分析计算问题的跨音速流场计算结果及其与设计计算问题结果的比较。数据表明两种计算结果紧密相符。
In this paper, the analysis of the disturbance propagating in the impeller flow field further clarifies that the supersonic solutions with M_m <1.0 and M_m> 1.0 can be obtained by the conventional algorithms for both types of calculation problems. The cross-over Sonic Velocity Field Calculation Results and Comparison with Design Calculation Problems. The data shows that the two calculations closely match.
