| 摘 要： | 以CFD软件FLUENT为工具对超临界水堆的三维带交混翼的方形单通道模型进行了数值模拟.模型考虑了交混翼的仰角对于通道内温度分布及流场的影响,结果表明,交混翼造成流体绕流,使得流道内冷热流体混合,从而使得流道内流体的温度分布均匀,有效改善了燃料棒表面温度分布情况,降低热点温度;交混翼在15°、30°、45°和50°四种仰角情况下,30°仰角情况更有利于温度区域均匀.

| Abstract: | Three-dimensional rectangular channel with the mixing wine in supercritical water reactor was studied in the paper using the FLUENT software.The mixing wing elevation influence on temperature distribution and flow field were studied in the model.The results showed the mixing wing caused fluid circumferential flow,making flow hot and cold fluids mixed and fluid temperature uniform distribution,effectively improved the fuel rod surface temperature distribution and reduced hot temperature.Among the four cases of mixing wing elevation of 15,30,45 and 50 angle,30 angle is the best case in improving temperature distribution. |
