“…Here, the reduced dipole length jsj is typically set to a value of jsj 2 2∕3 [52,50]. This formulation has been used by Taylor and Ali [8], Johnston [11], and Panesi et al [12]. They all appear to have set both f 1 and f 2 equal to 1, but their papers are not clear on the subject.…”

“…More sophisticated hypersonic chemical models of atomic N employ a collisional-radiative (CR) approach and treat the various electronic states of N as independent species [4][5][6][7][8][9][10][11][12]. However, this requires reliable EII data for a large number of states.…”

“…Global ionization rate coefficients for hydrogen and nitrogen are presented in figures 12 and 13, respectively. Data previously published by Drawin [81] and Drawin and Emard [82] for hydrogen and Taylor and Ali [83] for nitrogen are also given. The rate coefficients in [81][82][83] were calculated using CR models taking into account the detailed electronic structure of the atoms considered.…”

A one-dimensional hydro-kinetic model is developed to study arc extinction in a low-voltage breaking device. In part 1 of this double paper, the data necessary for the implementation of the hydro-kinetic model are presented. The equilibrium composition of the plasma is derived from the law of mass action. Mixtures of air and materials ablated from the thermoplastic wall (PA66, monomer C12H22O2N2) and from the contacts (copper) are considered. Thermodynamic properties such as mass density, enthalpy and specific heat at constant pressure are then calculated. Transport coefficients (viscosity, electrical conductivity and thermal conductivity) are determined with the Chapman–Enskog theory. Concerning radiation, the net emission coefficient, corresponding to the power radiated per unit volume and per unit solid angle, is calculated. Finally, for chemical kinetics, a reliable set of reaction rate coefficients linking the chemical species of the plasma is compiled. Particular attention is paid to ionization and recombination of atomic species which are obtained with the ‘bottleneck’ method.

New electron-impact ionization (EII) data are presented for neutral atomic nitrogen. The atom is treated as a 67-state system, incorporating Rydberg values up to n 20. State-specific cross sections for the first three states are from published B-spline R-matrix-with-pseudostates results. Binary-encounter Bethe calculations have been performed for the remaining 64 states. These data are designed for modeling the hypersonic chemistry that occurs when a space vehicle enters Earth's atmosphere from beyond orbit. The cross sections have been convolved into state-specific thermal rate coefficients and fit with the commonly used Arrhenius-Kooij formula for ease of use in shock-heated air plasma models. Additionally, rate coefficients are provided for a reduced 10-state system for use in coarse-grain models. For a given collisional-radiative model, these fine-and coarse-grain data can be used to generate state-specific rate coefficients for three-body electron-ion recombination, the time-reverse process of EII.
