| 摘 要： | 通过采用子通道程序FLICA建模分析5×5棒束临界热流密度试验，并分别采用直接代入法(DSM)和能量平衡法(HBM)两种方法利用已有临界热流密度关系式获得计算的临界热流密度，并将计算的临界热流密度与试验获得的临界热流密度对比分析，探讨了棒束临界热流密度试验数据的处理方法。结果表明，在棒束临界热流密度试验数据与已有关系式计算数据的对比中，HBM是一种更合理的方法。

| Abstract: | The critical heat flux (CHF) test with a 5×5 bundle was simulated by FLICA, which is a subchannel thermal-hydraulic analysis code. Furthermore, the CHF data were predicted by the direct substitution method (DSM) and the heat balance method (HBM) with available CHF correlation, respectively. By comparison between the measured and predicted CHF data, it is demonstrated that the HBM is a more suitable method for comparison between the test bundle CHF data and those predicted with the available correlation. |
