Abstract:

In the article it has been examined an issue of flow stability of LPC last stages at design and varying operating modes. Different stages of steam turbines have been analyzed. Important dependences have been achieved, including flow fluctuation and stability zones, as well as dynamic stresses while changing the operational mode. Critical modes have been determined, which characterize flow separation for the examined stages.
