Axial Turbine Design Method with Uniform Flux along Radial Direction
Turbine design is a complex and empirical process.To reduce the difficulty of turbine design,this paper proposed a method with uniform flux along radial direction and verified its ad-vantages by the design case of E3 turbine.The results show that the through-flow design is basically consistent with the spanwise distribution of parameters in 3D CFD simulation.The results show that the through-flow prediction is basically consistent with the 3D CFD prediction.And the new design scheme reduces the secondary flow loss at the root of the first rotor and increases the turbine efficiency by 0.5％.The proposed through-flow design method has some advantages in improving calculating stability,reducing time cost and improving turbine aerodynamic performance.
