Abstract:

基于CFD通用计算程序Fluent,开发了多孔介质流固两相局域非热平衡模型,对PBMR-400满功率名义工况下稳态热工水力行为进行了分析。高温气冷堆堆芯的热工水力计算模型通常为带有强内热源宏观的多孔介质模型,Fluent程序本身的多孔介质模型为局域热平衡模型,无法恰当描述堆芯热工水力行为。通过开启Fluent的自定义标量场(UDS)功能并在动量方程上附加阻力源项,实现了局域非热平衡模型,能够精确地计算球床堆堆芯热工水力行为。CFD程序使用了非常精细的网格,可以计算更加精细的流场和温场分布。计算表明,Fluent的结果与国际上著名的球床堆热工水力程序THERMIX,TINTE符合较好,可以作为球床堆热工水力分析工具。
