Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 On the basis of more than 100 various calculations of three-dimensional turbulent steam flows, a three-dimensional model of blading of the control section flow part of the steam turbine K-325-23.5 high-pressure cylinder has been developed. The studies were performed using the methods and software developed in IPMash NAS of Ukraine for 3D flows modeling and flow parts profiling. The results and analysis of the final version of the new control section flow part of the steam turbine K-325-23.5 high-pressure cylinder are presented. The flow part of the proposed control section consists of three stages, in contrast to the original design with two stages. The efficiency of the developed flow part of the HPC according to the results of the computational studies carried out, accounting steam extraction, was 91.0% at the design mode without accounting losses on the valves and 85.8% accounting losses on the valves. The increase in the efficiency of the new flow part compared to the initial one is from 6 to 10% in terms of the circumferential efficiency and from 1 to 2 MW in power, depending on the operation mode  Product Description popup.authors popup.nrat_date 2020-04-02 Close
