| Abstract: | Applying automatic aerodynamic optimization method of 3D cascade,the first stage nozzle of E~3 turbine was optimized for the maximization of the total pressure coefficient by constraining the mass flow rate and total pressure ratio.The total pressure coefficient of the optimum design has 0.8% higher than that of reference design.The optimal design blade shows a better aerodynamic performance than that of reference design.The result demonstrates that the method has good performance and is adapted to the aero... |
