The reversible axial fan is used to tunnel ventilation such as greate deep tunnel, railway tunnel and mine tunnel. Normally it supply the fresh air of exhaust polluted air and heat. In emergency, it exhaust poisonous gas and the high temperature heat for save peoples or properties. In this study, reversible axial fan in order to apply to transverse ventilation system such as U-smart way, GTX, Longer road tunnels. The blade section shape is designed as "approximate symmetric airfoil" which has bi-directional characteristic. This fan can proof against up to 300 ℃, over 1500 Pa(total pressure), has the 94% flow rate when the flow rate compares reversible flow case to forward flow case. In order to optimizing the reversible fan, I designed the fan through the analysis of 3-dimension viscous incompressible flow and through-flow analysis with ANSYS. All the fan performance tested in certified laboratory as of May 2011.
