| 摘要: |
| 从简化的或全NS方程出发，采用化学非平衡和热辐射非平衡模型，数值模拟了有烧蚀产物引射条件下小钝头锥体全目标流场与光电特性，旨在为防护设计提供气动物理环境数据。计算结果表明，本文流场模拟数据与实验数据基本吻合，壁面烧蚀产物引射和壁面催化特性对流场电子数密度均有量级影响。 |

| Abstract: |
| Adopting the models of chemical non-equilibrium and radiant nonequilib-rium，according to simplified or full Naver-Stokes equation，We numerically simulates whole target flow field and electronic-radiant characteristic of small blunted cone having ablative material injection with the purpose of providing the aero-physics data for protective design. The simulative results of flow field are compared with experimental data and good agreements are found. The numerical results show that the wall ablative material injection and the wall catalytic characteristic are considered，and have orders influence to electronic number density. |
