带芯子的碳-碳端头烧蚀外形计算

Calculation of ablation shape change of carbonca rbon nosetip with a core

摘要: 对电弧加热器试验条件下端头的烧蚀外形进行了数值仿真，考察了碳碳端头烧蚀外形随来流条件的变化规律，重点研究了将碳-碳端头体轴附近材料换成由另一种烧蚀速度较快的材料制成的芯子后的匹配烧蚀问题，揭示芯子对烧蚀外形的影响规律。

Abstract: This paper presents a numerical s imulat ion of nosetip shapechange during experiment on arcjet．The influence of flow conditions on nosetip shape change is investigated．Sensitivity studies are car ried out on matching ablation of the carboncarbon noseti
