Abstract

The aerodynamic characteristics of ACSR conductor with the large section were simulated with the fluid dynamics software in this paper. The slightly compressible viscous fluid and the Spalart-Allmaras turbulence model were used to modify the wind around the conductor. The numerical simulation results with the existing test results were compared and the effect of the roughness of the conductor on the aerodynamic characteristics was investigated. As the Reynolds number increases, the steady-state drag coefficients of the large section ACSR conductor decrease and tends to a stable value. The drag and lift coefficients decrease obviously in the range of 20000 to 40000 for the Reynolds number. The fluctuant lift coefficients of smooth boundary conductor are always larger than that of rough boundary model.
