abstract = "This study aims to model collisional-radiative transitions in hypersonic shock layers in a self-consistent manner. To achieve this purpose, sets of electronic state-resolved chemical kinetics are constructed for N2-O2 and N2-CH4 mixtures to study hypersonic atmospheric entry conditions to Earth and Titan. The constructed model is then applied to two-dimensional axisymmetric flows around a 3 m radius sphere including afterbody region. As a comparative group, the conventional quasi-steady-state model is considered with a reduced-order model closure on top of the electronic state-resolved approach to have consistency between the two models. The result shows that; (1) the electronic populations are not in the quasi-steady-state (QSS) near the shoulder and the afterbody and (2) this causes underprediction of the afterbody radiative heating.",
