Cooling Project Design for Magnetic Bearing of HTGR Helium Gas Turbine

Institute of Nuclear and New Energy Technology, Tsinghua University, Beijing, 100084, China

摘要: 电磁轴承是高温气冷堆立式氦气轮机系统的重要组件之一。本文针对高温气冷堆氦气循环发电中的高温电磁轴承,设计了4种综合冷却方案;采用前处理软件GAMBIT对电磁轴承腔体进行三维建模,使用流体力学计算软件FLUENT对模型进行了分析。模拟结果表明,通过合理的设计及优化,腔体可以得到有效冷却,并能将腔体温度控制在设备运行要求范围之内。

Abstract: Magnetic bearing is an important part of High Temperature Gas-cooled Reactor （HTGR） helium gas turbine. 4 cooling project designs are put forward for the high-temperature magnetic bearing of HTGR helium gas turbine. A three-dimensional model of magnetic bearing chamber is set up by GAMBIT, and analyzed by general computational fluid dynamic software——FLUENT. The simulation results show that the magnetic bearing chamber is cooled effectively by the improved design of cooling system, and its temperature is under control.
