| Abstract: |
| 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. |
