Abstract

Self-consistent models for homogeneous discharges are illustrated considering N2 as a case study. In particular the coupling between vibrational-dissociation kinetics, electronic kinetics and Boltzmann equation is illustrated. Extension of these models to hypersonic conditions is finally discussed.
