摘　　要：燃料棒的壁面温度是反应堆设计和运行过程中需要关注的重要参数之一。本文利用子通道程序对燃料棒壁面温度进行模拟,通过与实验数据对比,分别分析了子通道程序中的单相和两相换热模型。单相换热模型中,采用适用于棒束的Weisman公式与常用的D-B公式对比计算并最终选用Weisman公式。两相换热模型中,选用RELAP4公式包进行计算并对其判断准则做了简要分析。最终通过对空泡份额模型的对比,选择了Modified Armand模型,获得了较为准确的计算结果。The wall temperature of the fuel rod is one of the important parameters in the reactor design.In this paper,the sub-channel code is used to simulate the wall temperature of the fuel rods.By comparing with the experimental data,the single-phase and two-phase heat transfer models in the sub-channel code are analyzed separately.In the single-phase heat transfer model,the Weisman formula for the bundle is compared with the commonly used D-B formula and the Weisman formula is finally selected.In the two-phase heat transfer model,the RELAP4 formula package is selected for calculation and its judgment criteria is briefly analyzed.Finally,by comparing the model of the void fraction,the Modified Armand model is selected and the more accurate calculation results are obtained.
