| Abstract: | The aero dynamical property and the construction of counter - rotating axial flow fan are researched. According to the theory of aerodynamics axial flow fan, the hub ratio of counter- rotating axial flow fan is optimized and researched. Optimizing Excel between efficiency and hub ratio is built up. After considering the flow, total pressure, diffusion factor etc., the Excel of efficiency and hub ratio is created. With the powerful calculation function of the Excel, the efficiency under different hub ratio is analyzed and compared. Other structural parameter is fully considered too. the optimum hub ratio is confirmed. |
