Outline of Final Research Achievements

Thermal response of carbon-based and char materials in an aerodynamic heating environment was studied experimentally and numerically. Radiative transfer in the materials was modeled using an effective radiative conductivity, which was evaluated through a radiative extinction coefficient deduced from a ray-tracing calculation using the X-ray CT models of the materials. Aerodynamic heating experiments were made using JAXA arcjet wind tunnel facilities, and the thermal response of the material’s test specimen was numerically simulated using the radiative conductivity model. Comparison of in-depth temperature between calculation and measurement showed that overall trends in the measured time history of the temperatures was reproduced for all the materials examined in this study when the radiative conductivity was included in the calculation, suggesting that the radiative transfer within the low density carbon material can be modeled by the proposed method in this study.
