摘要
利用计算流体力学软件对部分气象参数组合时的架空输电线翼型雾-雨混合凇形成过程进行了数值模拟。结果表明,在风向垂直不可扭转导线的迎、背风面形成冰厚差距大的翼型冰;不同空气相对湿度和风速对导线覆冰的程度以及密度、厚度均有一定的影响。
The airfoil mixed-phase ice accretion on overhead lines was simulated by using the computational fluid mechanics software, and the results suggest that the airfoil ice with big thickness disparity tends to form on the windward side and the lee side of the conductor when the direction of wind is vertical to that of the conductor. It also suggests that the meteorological elements such as relative humidity and wind velocity have impact on icing process, density and thickness.
