Description

A novel collisional-radiative model for air plasmas is developed, with particular attention paid to the modeling fidelity for heavy particle impact excitation and associative ionization. The model is compared with a number of shock tube experiments, and is then used to explore the dynamics of associative ionization and electron impact ionization.
