A NUMERICAL INVESTIGATION OF ROTATING INSTABILITY IN STEAM TURBINE LAST STAGE

A NUMERICAL INVESTIGATION OF ROTATING INSTABILITY IN STEAM TURBINE LAST STAGE

Show other versions (1)

In the present study, the unsteady flow phenomenon (identified as rotating instability) in the last stage of a low-pressure model steam turbine operated at very low mass flow conditions is studied through numerical investigations. This kind of instability has been observed previously in compressors...
