| Abstract: | Based on the full radial-equilibrium equation,a multi-section aerodynamic design method and a 3D blading method for multi-stage axial-flow turbine were developed.The aerodynamic design for a four-stage axial-flow turbine was carried out by using the present methods and the 3D flow in the designed turbine was computed by using a 3D steady RANS solver.The results show that the aerodynamic design results agree well with the 3D computational results. |
