凝汽式汽轮机在变工况下流动状态的判别

Judgement Theorem for Subsonic or Supersonic Flow State of Condensate Turbine at Off-Design Condition

从汽轮机的基本工作原理出发 ,得出在临界状态下 ,临界压力与临界流量和初温平方根之积成正比变化等重要结论 ,用这些结论可确定汽轮机变工况后流动状态。不仅简化了汽轮机的变工况计算 ,而且丰富了汽轮机的变工况理论。参

Based on steam turbine's basic working principle, we give the important conclusion that at the critical state, critical pressure is proportional to its critical flow and square root of initial temperature, which can be used to determine the turbine flow state of off design condition. It not only simplifies the calculation of turbine off design, but also riches the turbine off design theory. Refs 3.
