摘要：

The modeling of a supersonic air nozzle flow is presented and compared with measurements at the nozzle exit. Shortcomings of state-of-the-art models for the kinetic scheme and energy exchange terms are discussed. In particular, the significant influence of an accurate modeling of vibrational-translational and vibrational-vibrational energy exchanges is shown. Conversely, the choice of the model for the kinetic scheme and for the chemical-vibrational energy exchange term only has a small influence on the results.
