Abstract

Based on steam turbine’s basic working principle, we draw the conclusion that at the critical state, critical pressure is proportional to its critical flow and square root of initial temperature. Part of the Sttla flow experimental curve is verified theoretically and an improved Flügel formula with a higher accuracy is proposed. As a result, not only the calculation is simplified, but also the theory of steam turbine’s varying operation conditions is enriched.
