从耦合辐射的轴对称热化学非平衡Ｎ－Ｓ方程出发，采用双温度、１１组元反应气体模型，耦合“线－线”精细辐射模型，利用隐式ＮＮＤ有限差分格式和时间预处理技术数值求解了ＦＩＲＥＩＩ飞船热化学非平衡辐射流场，得到了有关辐射热和辐射光谱计算结果，并与有关文献的实验结果和计算结果进行了比较。
Based on the axisymmetric thermo-chemical unbalance N-S equation of coupled radiation, a dual-temperature, 11-element reactive gas model was used to couple the “line-line” fine radiation model. The implicit NND finite difference scheme and time preprocessing technique The thermochemical non-equilibrium radiation flow field of FIREII spacecraft was solved and the calculation results of radiant heat and radiation spectra were obtained. The experimental results and the calculation results of the related literature were compared.
