Повышение эффективности работы 2-й ступени ЦВД турбины К-325-23,5 при нерасчетных углах обтекания потока

Abstract

The results of the numerical research of the 3D viscous flow in the flowing part of the compartment, which consists of the first two stages of the high-pressure cylinder of steam turbine K-325-23,5 are presented. A new form of blade of the second stage directing device is offered. The application of this form, which is insensitive to the unsettled angles of the flow accumulation, has allowed to significantly improve gas-dynamic efficiency of the flowing part.
