抗爆容器内爆炸流场数值模拟

摘要

Numerical results of the time-dependent behaviors of blast flows in a closed blast-resistant container with hemisphere roof and cylinder wall are presented.Results obtained using a total variation diminishing (TVD)scheme are compared to experimental results. The numerical results are in good agreements with experimental results.%采用计算流体动力学中的二阶精度TVD差分格式和特殊算子分裂法，按轴对称问题，对半球顶圆柱筒密闭式抗爆容器内部爆炸流场进行了数值模拟。计算得到的容器壁面载荷分布与实验结果基本一致。不同时刻爆炸流场压力分布图像清晰地描述了容器壁面的冲击波加载过程。
