摘　　要： 针对24对棒的多晶硅还原炉底盘的温度场均匀化问题,结合大型多晶硅还原炉的研制要求,应用Ansys 13.0中的Fluent对多晶硅还原炉底盘的辐射、导热和对流的传热过程进行了模拟分析,对不同进口流量(225 t/h、170 t/h和125 t/h)的还原炉底盘进行了流场模拟,得到不同流量情况下的还原炉底盘内部流场的速度场、温度场和压力场。结果表明:进口流量越大,底盘内部流场总温度越低,流体能量越低;进口流量越大,阻力降越大。综合考虑温度场和阻力降,进口流量取170 t/h是最优值。 In order to solve the problem of the temperature homogenization in reduction furnace chassis with twenty four silicon rods, the software Fluent in Ansys 13.0 was used to simulate the heat transfer process in the chassis of the furnace. Three different rates （225 t/h, 170 t/h and 125 t/h）of inlet flow of the chassis were simulated re- spectively, and the velocity field, the temperature field and the pressure field for each rate of inlet flow were ob- tained. The result revealed that the bigger rate of inlet flow, the lower temperature of the internal fluid field accom- panied with the bigger pressure drop. Finally, with the consideration of both temperature field and the pressure drop, the optimum value for the rate of inlet flow was 170 t,/h.
