| الوصف: | Formulas for evaluating the relative internal efficiencies of turbines that have not been designed as yet are given in many publications. Such assessments are required at the first stages of development and calculation of the thermal process circuit of a new steam turbine unit. The above-mentioned formulas are given without indicating the author’s name, particular initial material, and evaluation accuracy. To give an answer on these questions, the relevant publications were analyzed, and the results from calculations of relative internal efficiencies carried out using the published formulas and obtained from the hs diagrams of already designed turbines are compared. It is determined that Professor B.M. Troyanovskii, a well-known scientist specializing in turbines, is the author of these formulas. It is shown that these formulas give the “upper” (the best) estimate of efficiency. Formulas having the same structure as those of Troyanovskii but yielding a mean estimate with respect to already designed turbines are proposed. The results from the performed comparison are aimed at helping the developers of thermal process circuits for new steam turbine units to select the values of relative internal efficiencies of the cylinders for a turbine that has not been designed as yet. |
