摘 要:风流过一个通有电流的导体线圈,线圈的温度会降低。利用 CFD 计算技术,对由风速、线圈材料、线圈热功率等参数引起的温度变化进行了研究。在风速为 1 m•s-1 ~ 50 m•s-1 范围内,采用标准 k-ε 湍流模型,对通电线圈周围的热流场进行了数值模拟。结果表明:随着风速增大,线圈温度降低;随着线圈产热功率增加,线圈温度随之升高;线圈尺寸增大,温度升高;线圈材质对线圈温度没有影响。

Abstract:When air flows through a conductor coil with current,the temperature of the coil will decrease. The temperature changes caused by the following parameters,such as wind speed,coil material,coil thermal power etc are studied by using CFD calculation technology. In the wind speed range of 1 m•s-1 ~ 50 m•s-1 ,the standard k-ε turbulence model is used to make numerical simulation on the heat flow field around the current coil. The results show that the coil temperature decreases with the increase of wind speed,the coil temperature increases with the increase of coil thermogenic power,the coil temperature increases with the increase of coil size,and the coil material does not affect the coil temperature.
Keywords:wind speed;current-carrying coil;CFD
