In this method, the arc-jet freestream condition in the test section is evaluated theoretically by calculating the flows in the arc-jet wind tunnel. The thermal response of the ablator is calculated by loosely coupling the shock layer computational fluid dynamics code and the two-dimensional version of the ablation code using the arc-jet freestream condition so evaluated. This method is applied to heating tests conducted in the 1 MW arc-jet wind tunnel for a single set of operating conditions. The influence of catalysis on the ablating surface and the effect of nitridation and surface roughness on the thermal response of the ablator are investigated. Comparison of the calculated and measured temperature profiles at the ablating surface suggests that the measured temperature profile can be reproduced by assuming a low catalytic efficiency for the surface. It is found that the nitridation reaction moderately increases the surface temperature, and that the effect of surface roughness is small under the present operating conditions.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
