TL;DR: In this paper, the authors have calculated the net emission coefficient of air plasmas at atmospheric pressure in the temperature range between 300 and 40,000?K, in the assumption of local thermodynamic equilibrium and isothermal Plasmas.

TL;DR: In this article, the authors compared the results obtained for pure gases (CF3I, CO2, N2, air and N2) with the collision integral database by using the most accurate and recent cross-sections or interaction potentials available in the literature.

TL;DR: In this article, the authors deal with properties of air thermal plasmas containing vapours of iron, silver or copper, for temperatures ranging from 2000 to 30 000 K. The results are computed for various values of pressure, plasma size and proportions of vapours.

TL;DR: In this article, the properties of air-aluminum thermal plasmas have been investigated for complete modeling of arc systems involving aluminum contacts, assuming thermal equilibrium and correspond to the equilibrium composition, thermodynamic functions, transport coefficients including diffusion coefficients and net emission coefficient representing the divergence of the radiative flux in the hottest plasma regions.

TL;DR: In this paper, several mixing rules for mixtures of argon or air with metallic vapours are compared with relations deduced from physical consideration and some general behaviour is given in conclusion: mixing rules are good for electrical conductivity, viscosity and net emission coefficient.
