| 摘 要： | 把空度概念运用于压力容器上腔室的流场计算中，以３００ＭＷ核电站ＰＷＲ压力容器上腔室的１∶４模型为例进行了模拟计算和结果分析比较，证实了把空度概念运用于上腔室流场计算的作用。最后把流场计算结果与在３００ＭＷ核电站ＰＷＲ压力容器上腔室的１∶４可视化模型中实测的流速结果作了分析比较，本程序的计算结果在上腔室的中部，尤其是在出口管嘴附近与实验数据符合较好，具有一定的工程应用价值。

| Abstract: | This paper has employed Flow Fraction(FF) in the calculation of upper plenum flow field with a 1:4 scale upper plenum model of a 300MW PWR as an example to carry out the numerical calculation, the result analysis and the comparison, showing the effective FF in the calculation of the upper plenum flow field. The calculated result is compared with that measured in the simulated experiment. The flow field in the middle part of the upper plenum, especially that near the outlet nozzle of the upper plenum, agrees with that of the experiment very well. So the calculation has some engineering application values. |
