The Multiobjective Optimum Design Method for a Radial-axial Flow Turbine With the Optimum Criteria of Blade Twist at Outlet of Blades

Chen Lingen  
This paper provides a multiobjective optimum design method for a radial-axial flow turbine stage with constraints of engineering construction conditions, in which, five parameters in mean radius, α_1, β_2, μ, -, m=u_2/w_2cos;2,and the criteria of blade twist at outlet of blades, are taken as design vari-ables, and internal efficency of design condition and total weight as objective functions. The model presented is a nonlinear multiobjective programming problem of two objective functions with 29 constrained functions and 6 variables. The statement of the optimization problem and some analytical results of single and multiobjective optimization for all types of twisted blades are also provided. The results of calculation show the method is valid and effective.
