| 摘 要： | 使用Fluent14.5两流体模型中的RPI(Rensselaer Polytechnic Institute)壁面沸腾模型,对堆芯燃料棒束通道内过冷沸腾现象进行数值模拟,得到了通道内的流场、温度场以及空泡份额的分布,分析了定位格架和搅混翼的存在对热工水力特性的影响。数值结果表明,格架的存在会造成很大的压降,而搅混翼会对流场、温度场和空泡份额分布产生显著影响;RPI壁面沸腾模型的模拟结果与Bartolemei试验数据符合很好。

| Abstract: | The RPI （Rensselaer Polytechnic Institute） wall boiling model, embedded in the context of two-fluid model of Fluent14.5, was applied to simulate subcooled boiling in core fuel bundle channel with mixing vanes and space grid. The subcooled boiling key parameters including flow field, temperature field and void fraction distribution were obtained. The analysis of the effect of mixing vanes and space grid on flow channel thermal-hydraulic characteristics was conducted. It is shown that the existence of space grid can cause a large pressure drop, and mixing vanes have a great influence on the key parameters of flow field and temperature field. The results of RPI model show a good agreement with Bartolemei experiment data. |
