Design and Performance Study of Asymmetric S-shaped Airfoil for Reversible Axial Fan |
| |
| Abstract: | S shaped blades are the ideal blade type used for reversible fans.On the basis of the previous studies,the NACA series blade was selected as the original airfoil in this paper,based on it,several new types of asymmetric S-shaped airfoil were designed with double-headed and double wings.The numerical simulation was conducted and the results were analyzed respectively for the reversible fans made up of the above different types of S-shaped airfoil.Through comparing the flow field distribution in different fans,an airfoil suitable for the reversible axial fans for metro was achieved with better forward and reverse performance under the design condition. |
