Research on the influence of boundary conditions on the simulation of the aerodynamic coefficient of power transmission towers

Abstract

The shape coefficient is an important design parameter of high voltage power transmission tower. It can be obtained by means of CFD simulation. The inlet boundary condition will affect the calculation accuracy. In this paper, the turbulent inflow and the uniform inflow are used respectively. By comparing the calculation results of the two conditions, the simplified inlet condition of uniform flow is evaluated whether it is reasonable.
