炭素アブレーション層の放射吸収効果を含む粘性衝撃層の解析

抄録

We calculated the flow-field and surface response condition of a planetary probe entering the Jupiter atmosphere, Within the region behind a detached shock wave, the blunt nose is heated to high temperature. So that, the numerical results were obtained under a viscous-shock-layer analysis. To protect the probe against high temperature condition and to reduce the heat flux, which includes convectional and radiative heat transfer, we used the ablation of C/C composite materials. This simulation included mass injection, radiative transfer, diffusion, and viscous effects. The radiations included were molecular bands, atomic lines, and continuum processes. It was found that carbon ablation materials were effective in reducing the radiative heat flux.
