| 摘 要： | 1引言大粘度（大r）和大系数（ss和sc）法是处理流动区域中障碍物的常用方法山。但当流动区域中障碍物数量较多时，宜采用空隙率来模拟障碍物，如模拟反应堆流动传热的商用程序COMMIX［’］。我们根据空隙率模拟的基本概念，针对采用交错网格的压力校正法，自行编制了多障碍物流动传热三维计算的全部源程序代码，应用于某核反应堆钠池流动传热的数值模拟，获得了比较合理的结果。2数学模型和数值方法2．1控制方程空隙率修整的质量、动量、能量及湍流动能与耗散率的守恒方程通式的三维柱坐标形式为其中中一1，。，。，。，T，k，。分别表…

| Abstract: | Three-dimensional numerical model, which employed porosity factors to simulate the effects of obstacles in the fluid domain, was developed. Computer code-FASTOR-3D, based on SIMPLE algorithm and staggered grid scheme, was initiated and verified with several benchmark solutions. Application of this code on heat transfer and flows in sodium pool of a fast breeder reactor, turned out meaningful database. The vast numerical result is visualized with affiliated software DV which converts flow and temperature fields into vivid colors for convenient analysis. |
