摘要

熔盐与超临界二氧化碳（S-CO

）换热器是连接一二回路的关键设备，而熔盐的换热能力优于S-CO

，因此，两侧需要的传热面积是不同的。Z形流道和翼型翅片流道耦合的印刷电路板式换热器（PCHE）可以匹配熔盐和S-CO

的换热，而针对这种换热器的研究比较少。采用SST k-ω湍流模型对熔盐和S-CO

的耦合换热进行数值模拟研究。首先，基于熔盐和S-CO

的实验数据验证了数值模拟方法的精确性；其次，分析了熔盐和S-CO

的耦合换热特性，发现在耦合换热的影响下，S-CO

侧对应区域的换热强度会随之增强；分析了熔盐侧在不同工况下的沿程流动换热特性，随着Re增大，Nu增大，并且由于流道是Z形的，轴向摩擦阻力系数f显示出波动性变化；最后拟合了熔盐侧在3 000

7 000下的Nu关于Re的经验关系式，拟合的关系式跟计算结果偏差在1.2%左右。
