| 摘 要： | 采用一维球对称辐射流体力学方程组,构建直接求解辐射输运方程的一种数值方法,得到强爆炸早期火球发展过程中火球阵面、弹壳冲击波的形成发展过程.计算结果与Brode结果进行对比,二者一致,证明数值方法的合理性.数值模拟爆炸源区不同当量、不同密度以及不同爆炸高度等条件下强爆炸早期火球发展过程中火球阵面、弹壳冲击波的形成发展过程,对计算结果进行比较分析.

| Abstract: | One-dimensional radiation hydrodynamics equations with spherical symmetry are used to study early development of fireball front and ease shocks in strong explosion.Numerical method for radiation transport equations is established.The calculation results agree well with Brode's.Early formation of fireball front and case shocks in strong explosion at different yield,density in explosion zone and altitude are simulated numerically. Calculation results are analyzed. |

| Keywords: | fireball of strong explosion radiation hydrodynamics numerical simulation |
