“…While for the order l odd (i.e. l = 1 or 3), the latter is dominant in determining the collision integrals [15,20,34,35]. In this study, an empirical mixing rule proposed by Murphy [34,36,37] is adopted to calculate the total collision integrals:…”

“…where the subscripts 'el' and 'in' denote the collision integrals derived from the elastic and the inelastic interactions, respectively. The charge-exchange cross-section for collision between neutral particle (X ) and ionized particle (Y z+ or Y z− ) is small compared with the elastic collision cross-section [15,20,34,35], and is neglected in this paper.…”

“…Unless otherwise specified, all the results presented in this work are obtained by considering the graphite formation. The Debye-Hückel correction, an adjustment to the usual expression for the Gibbs free energy representing the additional effect of electrostatic interactions between charged particles [15], is also taken into account. The required thermodynamic data for atoms and their positive ions are calculated from the internal partition functions, as are derived from the electronic level energies and degeneracies taken from the National Institute of Standards and Technology (NIST) database.…”

This paper is devoted to the calculation of fundamental properties of CO 2 mixed with C 2 F 4 . The species composition and thermodynamic properties (mass density, entropy, enthalpy and specific heat at constant pressure) are based on Gibbs free energy minimization. The transport properties (electrical conductivity, viscosity and thermal conductivity) are calculated by the well-known Chapman-Enskog method. The Lennard-Jones like phenomenological potential and some recently updated transport cross sections are adopted to obtain collision integrals. The calculation is developed in the temperature range between 300 and 30 000 K, for a pressure between 1 to 16 bar and for several C 2 F 4 proportions. Transport coefficients for CO 2 are also compared with previous published values, and the reasons for discrepancies are analyzed. The results obtained for CO 2 -C 2 F 4 mixtures provide reliable reference data for the simulation of switching arcs in CO 2 circuit breakers with the ablation of PTFE.

“…[58][59][60] This phenomenological potential allows direct evaluation of internally consistent complete sets of collision integrals for different atmospheres and can provide more accurate estimation of the interaction potential by recent comparative study performed for some benchmark systems. 61 This model potential can be defined in terms of fundamental physical properties of involved interacting partners (polarizability a, charge, number of electrons effective in polarization). The values used here for heavy species are listed in Table II and all these data are taken from the NIST Computational Chemistry Comparison and Benchmark Database 62 and previous estimation of Ref.…”

This paper deals with thermodynamic and transport properties of SF 6 plasmas in a two-temperature model for both thermal equilibrium and non-equilibrium conditions. The species composition and thermodynamic properties are numerically determined using the two-temperature Saha equation and Guldberg-Waage equation according to deviation of van de Sanden et al. Transport properties including diffusion coefficient, viscosity, thermal conductivity, and electrical conductivity are calculated with most recent collision interaction potentials by adopting Devoto's electron and heavy particle decoupling approach but expanded to the third-order approximation (second-order for viscosity) in the frame of Chapman-Enskog method. The results are computed for various values of pressures from 0.1 atm to 10 atm and ratios of the electron temperature to the heavy particle temperature from 1 to 20 with electron temperature range from 300 to 40 000 K. In the local thermodynamic equilibrium regime, results are compared with available results of previously published studies. V C 2012 American Institute of Physics. [http://dx.
