| 摘 要： | 球形燃料元件与水冷堆相结合,因其突出的优势受到广泛的关注,成为新概念堆型探索方向之一.文中以水为工质,对多孔介质中Forchheimer区和湍流区下阻力压降进行研究,并将其与经典Ergun型方程的计算值进行了比较和分析.结果表明,湍流区中Ergun型方程的值与实验值出现很大偏差,但二者之间有比较相似的总体趋势.在此基础上,修正了湍流区中Ergun型方程中的常系数,得到了合理的预测模型公式.

| Abstract: | The combination of spherical fuel elements and water-cooled reactor,which highlight the advantages of taking a wide range of concerns,is a new concept of reactor type.This paper,using water as working fluid,studied the porous media flow resistance pressure drop of single-phase under forchheimer zone and the turbulent zone,and compared with the Ergun equation.The results show that Ergun equation and experimental values show great deviations in the turbulent zone,but the two general trends were more similar.Thus,we revised the constant coefficients of Ergun equation in turbulent zone,obtained a reasonable prediction model formula. |
