摘　　要：采用基于多孔介质模型的ＦＡＳＴＯＲ－３Ｄ程序研究快堆钠池稳态流场和温度场。对该程序采用的Ｋ－ε两方程湍流模型和常粘度系数模型进行了讨论。计算结果表明：导热系数和比定压热容对钠池内部温度场没有影响，仅在钠池边界附近对温度场有微小影响；２种模型的计算结果相近，但采用常粘度系数模型计算易于收敛且计算时间较短。Based on SIMPLEC algorithm and staggered grid scheme, a three dimensional flow and heat transfer computer code, FASTOR 3D, is developed to investigate the flow and heat transfer in a sodium pool of a fast breeder reactor. Two equation K ε turbulence model and constant viscosity model are compared. It is found that the numerical results are almost same and the constant viscosity model is easy to converge and saves the CPU processing time.
