现有的各国文献中很难找到计算向心透平反动度的适用方法。目前设计向心透平时,大多数利用试选法确定其反动度。本文提出了一种根据透平叶轮中的气流加速因子(?)来计算向心透平反动度的方法。文中将向心透平的反动度分解成气动反动度与惯性反动度两个独立的组成部分,分别讨论了它们的作用与计算方法。从而不难计算出所需的向心透平反动度的具体数值。 It is hard to find a suitable method to calculate the reactionary rate of the centripetal solution to the existing literature in various countries. At present, when designing a centripetal system, most use the trial-and-error method to determine its reaction. In this paper, a method to calculate the centripetal turbulence according to the acceleration factor (?) In the turbine impeller is proposed. In this paper, the reaction of CPT is decomposed into two independent components of aerodynamic reaction and inertia reaction, and their roles and calculation methods are discussed respectively. It is not difficult to calculate the required specific values ​​of the centripetal turbine reaction.
