Abstract
Numerical simulation of transmission lines’ movement can reveal the variation of aerodynamic force with conductor vibration. The fluid-structure interaction is considered and, and the software FLUENT is used to numerically analyze the model responses of 0.75D crescent-shaped iced conductor with wind attack Angle of 180° based on the k-ω SST turbulence model. The numerical simulation results of unsteady galloping of the iced conductor are compared with the galloping response of displacement time history analysis. The results show that the results of the fluid-structure interaction analysis are consistent with the quasi-steady analysis.
