In this paper, aerodynamic performance of double-flow controlling stages for ultra-supercritical 1 000 MW turbine which includes inlet chamber, controlling stages, outsider of the reverse flow chamber and export mixed flow chamber was investigated by using CFD software. The analysis result shows that the loss of total pressure in inlet chamber was lower under operation condition, the high aerodynamic performance of controlling stages could achieve the goal of thermodynamic design.
