The effects of remodeling of stator on aerodynamic performance of compressor are numerically investigated based on 15 th stage of a heavy gas turbine compressor , the end-bend blade technology was adopted for retrofitting of stator in simulation.Numerical simulation results show that the end-bend blade can control effectively the separation flow at the corner zone,and increase the efficiency and the pressure ratio greatly .
