This paper explores the ability of the Kurganov, Noelle, and Petrova numerical scheme included in the rhoCentralFoam solver of the OpenFOAM^™software to model strong explosion processes, using typical gas dynamics concepts. The main objective of this study was to obtain a numerical tool to simulate strong explosions. Once the generated blast waves and their propagation were simulated, the numerical results were compared with those of Sedov’s analytical solutions. Both numerical and analytical results were obtained from applications to geometrically cylindrical and spherical explosions. All comparisons were focused on the shock position as time elapsed and on the evolution of flow properties after the shock wave.

本文探讨了OpenFOAM ^™软件的rhoCentralFoam解算器中包含的Kurganov，Noelle和Petrova数值方案使用典型的气体动力学概念对强力爆炸过程进行建模的能力。这项研究的主要目的是获得一个数值工具来模拟强爆炸。一旦模拟了爆炸波及其传播，就将数值结果与Sedov的解析解进行了比较。数值和分析结果均来自几何圆柱和球形爆炸的应用。所有比较都将重点放在随时间流逝的冲击位置上，以及冲击波后流动特性的演变上。
