摘　　要：采用CFD方法研究了具有点蚀损伤的输电线的气动参数模拟问题。采用GAMBIT软件对腐蚀输电线进行了计算域网格划分,基于Reynolds stress湍流模型对腐蚀输电线的流场进行了数值模拟,获取了腐蚀输电线的气动系数分布。结果表明:腐蚀输电线的外形对气动参数有一定影响,若点蚀坑数量较少,则对气动参数的影响有限。Numerical simulation of aerodynamic coefficients of transmission lines with corrosive pitting damages were actively investigated by CFD.Transmission lines with corrosive pitting damages were selected to mesh the computational domain by commercial package GAMBIT.The Reynolds turbulence model was used to carry out CFD simulation on the flow field of corrosive transmission lines.Furthermore,the distribution of aerodynamic coefficients of transmission lines with corrosive pitting damages were determined.The made observations indicate that the shape configuration of corrosive transmission lines have some influence on the aerodynamic coefficients.The effects corrosive damage are limited if the number of corrosive pitting damages is small.
