摘要
介绍了由美国洛斯阿拉莫斯实验室(LANL)和德国卡尔斯鲁厄研究中心(FzK)共同开发的三维计算流体力学程序GASFLOW的基本数学物理模型和数值计算方法。该程序主要用于分析核电站严重事故下安全壳内氢气、水蒸气扩散分布和燃烧。列举了该程序在德国Konvio型压水堆氢气安全分析中的应用。
Introduce the basic mathematical and physical models of multi-dimensional computational fluid dynamics （CFD） code GASFLOW, which is jointly developed by Los Alamos National Laboratory and Forschungszentrum Karlsruhe. The code is mainly used to analyze the distribution and combustion of hydrogen and steam in the containment under severe accident in NPP. The applications in a closed room and a German Konvoi-type PWR plants were presented.
