| 摘 要： | 本文提出了一个高超声速非烧蚀钝体尾流全流场的简化模型和简化的空气化学模型。该模型用于化学非平衡尾流积分电子密度与NO_2化学发光辐射等参数的计算。对于NO_2化学发光辐射既求得了整个频谱范围内的总辐射,也求得了分谱辐射强度。计算结果与弹道靶测量数据进行了比较,它们之间的一致性良好。

| Abstract: | A simplified flow field model and simple air chemical model for the chemical nonequilibrium wakes of hypersonic non-ablating blunt-body are presented. The models are applied to calculate the integrated electron density and NO2 chemiluminescence in the wakes. Numerical results of NO2 chemiluminescent emission over the wavelength region 0.4-1.2 and over any wavelength interval of interest are obtained. The calculated results are compared to the wake measurements in the ballistic region. The agreement between them is good. |
