中文摘要:
      目的 研究真空管道交通中磁浮列车悬浮电磁铁温度随管道内真空度及环境温度的变化规律。方法 建立三维电磁铁模型,利用Fluent软件研究真空度(0~80 kPa)、环境温度(283~323 K)对电磁铁温升性能的影响,并对Realizable k-ε和RNG k-ε 2种湍流计算模型进行对比。结果 电磁铁表面温度随真空度的增大而升高,当真空度超过60 kPa时,电磁铁表面温度快速升高。随着环境温度的增加,电磁铁表面温度呈近似线性关系增大。Realizable k-ε和RNG k-ε 2种湍流模型的仿真结果基本相同。结论 真空度和环境温度对悬浮电磁铁散热性能均有很大影响,在设计真空管道列车时,需考虑电磁铁散热能力,并采取相应措施。
英文摘要:
      The paper aims to study the temperature of suspension electromagnet of maglev train with vacuum degree and ambient temperature in the evacuated tube. The influence of vacuum degree (0~80 kPa) and ambient temperature (283~323 K) on heat dissipation performance of suspension electromagnet is studied with Fluent software. The Realizable k-ε and RNG k-ε turbulence models are compared. The results show that the surface temperature of the electromagnet increases with the increase of the vacuum degree. When the vacuum degree exceeds 60 kPa, the surface temperature of the electromagnet increases rapidly. The surface temperature of the electromagnet increases in an approximately linear relationship with the increase of the ambient temperature. The simulation results of Realizable k-ε and RNG k-ε turbulence models are basically the same. The vacuum degree and ambient temperature have a great influence on the heat dissipation performance of the suspension electromagnet. When designing the evacuated tube train, the heat dissipation capacity of the electromagnet should be considered and corresponding measures should be taken.
