The thermally and chemically nonequilibrium hypersonic flow around the MUSES-C reentry capsule was analyzed to evaluate the radiative heating environment. The typical reentry speed is 11.6 km/s at the altitude of 64 km. Since the radiative heating strongly depends on the vibrational-electronic temperature distribution, the energy relaxation mechanism for vibrational-electronic energy was clarified by investigating the contribution of each term for energy exchange between translational and vibrational-electronic energy. From this investigation it was found that the energy relaxation terms related to ions are dominant under such a severe reentry heating environment such as the MUSES-C reentry flight condition. The predicted value for the radiative heat flux at the stagnation point amounts to 1.4 MW/m(sup 2). In the afterbody region, the radiative heat flux is relatively small, and at the base, it is less than 1 percent of the stagnation point. All around the vehicle surface, the radiative heat flux is much smaller than the convective heat flux. The effect of ablation gas on the radiation was also assessed. It was also found that in the forebody region the effect of the ablative gas on the radiative heating environment for MUSES-C is not so significant but in the afterbody region the effect is relatively large. |
