本文在吴仲华教授提出的叶轮机械三元流动理论基础上讨论了多级透平的级间配合问题,推导了设计参数与气流参数间的关系式,作了多级透平的性能计算得到了一些可供参考的结论.从计算结果可见,可通过控制各截面的相对堵塞比来有效的控制各级叶片的通道形状及充分发挥各级透平的作功能力,并达到高的效率,当相对堵塞比接近1时效率达到最高。
Based on the theory of ternary flow of impeller presented by Professor Wu Zhonghua, this paper discusses the interstage coordination problem of multi-stage turbine, deduces the relationship between design parameters and air flow parameters, and makes some performance calculation of multi-stage turbine For reference, we can see from the calculation results that by controlling the relative blockage ratio of each section, we can effectively control the channel shape of each blade and make full use of the turbine’s work ability and achieve high efficiency. When relative Clogging up to close to 1 to achieve the highest efficiency.
