Abstract: Parametric modeling of the impeller which drove a small wind device was built by knowledge fusion technology. NACA2410 airfoil blade was created by KF language. Using technology of UG/KF secondary development for the automatic modeling of wind turbine blade, the program can read in the airfoil data files automatically and the impeller model entity can be generated automatically. In order to modify the model, the aerodynamic characteristics of the impeller were analyzed for getting aerodynamic parameters by Fluent. The maximum force torch and best parameters of impeller were calculated. A physical prototype impeller was manufactured and the correctness of the design was verified, and the error of force torch between simulation and experimental results is about 10%. Parameterization design of the impeller model greatly improves the efficiency of modeling and flexibility of the CAD system.
