摘要

为了给输电线路抗冰设计中冰雪厚度的估算及覆冰机理的研究提供理论依据

笔者从流体力学和热力学角度出发

建立全面的表征导线捕获过冷却水滴及冰面热传递过程的雾凇覆冰厚度预测模型。仿真结果表明

水滴与导线碰撞时的碰撞系数以及覆冰密度是影响预模型测结果精确性的关键参数

随覆冰时间增加雾凇覆冰厚度增长率逐渐减小

碰撞系数逐渐减小

水滴碰撞导线速度和冰面温度也随之减小

导致雾凇冰密度也逐渐减小。仿真和实验结果均表明

随圆柱体初始直径的增加

冰厚呈幂函数降低

模型预测结果与试验及现场观测结论一致。

Abstract

To provide theoretical basis for the estimation of ice thickness in anti-icing design and icing mechanism study of transmission lines

this paper proposed a thickness prediction model of rime ice accretion on a conductor.This model can be used to describe the capture process of super-cooled droplets by the conductor and the heat-balance state.Simulation results indicate that the collision coefficient and the ice density are the key factors to affect the accuracy of prediction;with the increase of icing time

all the increasing rate of rime ice thickness

the collision coefficient

the collision velocity of droplet and conductor

the density of the rime ice

and the temperature on ice surface gradually diminish.A measurement device based on rotating multicylinder was developed

and an experiment was conducted.Both simulation and experiment results show that the ice thickness decreases exponentially with the increase of cylinder diameter.
