摘要

为了研究覆冰导线在风荷载作用下的气动特性

笔者采用计算流体力学软件Fluent模拟覆冰导线周围的空气流场

并计算了不同覆冰厚度的导线在不同迎风攻角下的升力系数、阻力系数及扭矩系数

得到了覆冰厚度、风速等因素对覆冰导线气动参数的影响规律。结果表明

覆冰厚度对阻力系数、升力系数和力矩系数均有较大影响

但影响规律不尽相同。风速对阻力系数有较大影响

对升力系数和力矩系数的影响并不明显。计算所得的气动参数可为覆冰导线舞动研究提供参考。

Abstract

To understand the aerodynamic characteristics of an iced conductor under wind load

the air flow field around the iced conductor was simulated with the software Fluent.The lift coefficient

drag coefficient and torsional coefficient under different attack angles were calculated for the iced conductors with different ice thickness.The influences of ice thickness and wind speed on the aerodynamic parameters of iced conductors were obtained.The results show that the ice thickness exerts significant influence on the drag coefficient

lift coefficient and torsional coefficient.The wind velocity exerts great influence on the drag coefficient

but slight influence on lift coefficient and torsional coefficient.The computation results may facilitate the research of conductor galloping.
