Computational fluid dynamics (CFD) was used in this study to numerically simulate the heat removal and hybrid ventilation characteristics of a vertical dry storage cask for spent nuclear fuel. The parameters included a Grashof number of 1.0x1011, an approaching wind incidence angle of 0° or 45°, and a Reynolds number (Re) of (). As shown by the results, the buoyant airflow dominated the heat removal capability of the cask at low Re (). When the Re was increased to , the wind-induced channel airflow compromised the buoyant airflow, thus reducing the heat removal capacity of the cask. When the Re was, the wind-induced airflow dominated.

立式干式核燃料储存罐的除热和混合通风特性
在这项研究中,使用计算流体动力学(CFD)数值模拟了乏核燃料用立式干式储存桶的除热和混合通风特性。参数包括Grashof数为1.0x10 11,接近风的入射角为0°或45°以及雷诺数(Re)为 ()。结果表明,在低Re()。当Re增加到,风诱导的通道气流损害了浮力气流,从而降低了桶的散热能力。当Re是,风引起的气流占主导。
