A radiation model is developed to obtain evolution of band intensities according to the state-to-state (STS) approach by considering vibration-translation and vibration-electronic jumps and dissociation. Investigation of the behavior of a nonequilibrium N(2) gas flow behind a shock shows that the radiation intensity remains weak and the flow is far from radiative equilibrium. Similar intensities are predicted by pure STS and hybrid approaches based on existing radiation models. However, the coupling between physicochemical and radiative processes increases with radiation intensity.
通过考虑振动-平动、振动-电子跃迁和解离,开发了一种辐射模型,以根据态-态(STS)方法获得谱带强度的演变。对激波后非平衡N₂气流行为的研究表明,辐射强度仍然较弱,且气流远未达到辐射平衡。基于现有辐射模型的纯STS方法和混合方法预测出了相似的强度。然而,物理化学过程与辐射过程之间的耦合随着辐射强度的增加而增强。
