Abstract: The air flow field around the iced conductor was simulated by means of FLUENT model of ANSYS12 software. The lift coefficient, drag coefficient and torque coefficient under different attack angles were calculated for different bundle conductors. Firstly, the numerical results of the tri-bundled conductors in Hubei Zhongshankou were compared with the wind tunnel test data to verify the accuracy of the calculation model, and then the aerodynamic parameters of part of bundled conductors were calculated and analyzed by this calculation model. The influences of ice thickness, ice shape and wind speed on the aerodynamic parameters were obtained. Meanwhile, the influences of ratio of the conductor spacer and diameter on wake were analyzed. The obtained aerodynamic parameters can provide load support for the research of conductor galloping.
