| Abstract: | The use of two-dimensional inverse design method for impeller blades shape is introduced. With the experiment, the wing blades are changed into two-dimensional plate. blades successfull. The new model fans have the characteristics that high efficiency and save energy. Particularly, the b.lades wearability and service life of the fan had been improved. |
