摘要(Abstract)：

采用CFD（计算流体力学）数值模拟方法研究了特高压圆管输电塔的气动力特性。基于SOLIDWORKS和ICEM软件建立了输电塔整塔的精细化CFD数值模型，采用基于RANS的SST k-ω湍流模型模拟输电塔周围的空气流动，重点分析了不同风速和风向角下输电塔各塔段的气动力系数，并将数值计算得到的各塔段阻力系数与国内外规范值进行了详细对比分析。研究结果表明：输电塔最高处的参考风速对气动力系数的影响很小；大部分塔身的阻力系数值关于风向角45°呈现对称状态；在45°～90°风向角内，阻力系数随着风向角的变化呈先减小后增大趋势，在60°达到最小值；塔身的升力系数几乎为0；数值模拟得到的大部分塔段（除塔腿及其相邻段）的阻力系数大于规范取值。
The CFD(computational fluid dynamics) numerical simulation is used to study the aerodynamic characteristics of a UHV steel tubular transmission tower. A refined CFD numerical model of the whole transmission tower is established based on SOLIDWORKS and ICEM. The airflow around the tower is simulated using the SST k-ω turbulence model based on RANS, and the aerodynamic coefficients of each tower section under different wind speeds and wind angles are analyzed. Moreover, the drag coefficients obtained from numerical calculation of each tower section are compared with standard values at home and abroad. The results of the study show that the reference wind speed at the highest point of the transmission tower has little effect on the aerodynamic coefficient; the drag coefficients of most tower sections symmetrically distribute with a wind angle of 45°； the drag coefficients tend to decrease and then increase with the change of wind angle from 45° to 90° and reaches the minimum at 60°； the lift coefficient of the tower is almost zero; the drag coefficients of most tower sections(except for the legs and adjoining sections) obtained from numerical simulation are greater than the standard value.
