“…Solving equation (1)(2)(3)(4)(5) iteratively together with the material data of nitrogen enable calculation of the arc temperature, radius, and the electric field. In some cases, due to scarcity of high pressure material data for nitrogen at high temperature, thermodynamic and transport properties of high pressure air are used [19][20][21]. From the calculated electric field, the arc voltage can then be estimated by assuming a fixed electrode voltage drop of 17 V for all filling pressures, based on previous works [9], [22].…”

“…Hence, only 2 mm, 4 mm, and 8 mm tube inner diameters are considered here. The equations along with the material dependent data of electrical conductivity, density, enthalpy, sonic velocity are solved iteratively [19], [21], [24].…”

“…In a thermal nonequilibrium flow, the different energy modes should be expressed in terms of their associated temperatures to distinguish their relevant contributions to the basic thermodynamic properties [86]. The thermodynamic properties of individual species, such as the enthalpy, entropy, and specific heats, can be calculated using the formulas from statistical thermodynamics [87], in which the partition-function approach is employed. According to quantum physics, the energy of a single atom or molecule is a discrete value, which can be calculated by its energy state i.…”

“…The computational complexity and cost of the calculation of two-temperature properties is significant, and often hinders the development of nonequilibrium plasma flow models. Remarkable progress has been achieved in the computation of nonequilibrium properties, from the classic work by Paik and Pfender [70,71] on argon properties; by Ramshaw and Chang [74] on ambipolar diffusion in multicomponent plasmas; and by Rat et al [75] on an improved theory for two-temperature transport properties; to the recent work by Colombo et al [27] on Ar-H 2 and N 2 -H 2 mixtures; by Meher et al [53] on the comparison of equilibrium versus nonequilibrium properties of nitrogen plasmas; by Zhang et al [101,102] on the comparison of different methods of computing two-temperature transport properties; and by Wu and collaborators [97] on SF 6 -Cu plasmas.…”
