针对快中子增殖反应堆钠池的流动传热特点,以质量、动量、能量守恒定律为基础,建立有关快堆钠池流动传热的三维数学模型。池内流动域中障碍物对流动和传热的影响采用空隙率和穿透率的概念来描述;钠池与其围护结构的传热关系采用耦合计算方法求解。编写了基于压力校正法和交错网格的三维流动传热模拟计算程序FASTOR-3D。该程序通过了若干经典算例的验证计算,并应用于实际的三维钠池流动传热模拟,获得了大量的预测数据。附属软件DV以色彩表达流场、温度场等三维物理量的大小强弱,实现了大批量数据的可视化分析。
Aiming at the characteristics of the flow and heat transfer in the sodium pool of fast breeder reactor, a three-dimensional mathematical model about the flow and heat transfer of fast reactors sodium pool is established based on the laws of conservation of mass, momentum and energy. The influence of the obstructions on the flow and heat transfer in the flow field of the pool is described by the concept of void fraction and penetration rate. The heat transfer relationship between the sodium pool and its envelope is solved by the coupled calculation method. FASTOR-3D, a three-dimensional flow heat transfer simulation program based on pressure correction method and staggered grid, was prepared. The program passed the validation calculation of several classical examples and applied to the actual three-dimensional sodium pool flow heat transfer simulation, obtained a large number of forecast data. Affiliated software DV to color flow field, temperature field and other three-dimensional physical strength of the size of the data to achieve a large number of visual analysis.
