“…On the other hand, the absorption of radiation in the cold regions at the edge of the arc is almost independent of the metal concentration when this concentration remains low (up to 10 %). Our results are similar to those of [14,19]. It should be noted that the results for silver are probably underestimated.…”

“…Various methods have been used to calculate the radiation of thermal plasmas. We can mention among them the method of partial characteristics [13], the discrete ordinate (SN) method [14] and finally the P 1 method [15]. Each of these methods uses simplifying assumptions about the spectral dependence of equation 3or spatial dependence and often both.…”

“…It is possible then to precompute all thermodynamic properties and store in the form of lookup tables as described in ( [5][6][7]). For simplicity, electrode erosion and ablation of wall material were neglected, making it possible to consider pure air arc discharge.…”

“…The model used to calculate the spectral radiation transfer (referenced as exact in this paper) can be characterized as a one dimensional DOM model and was more thoroughly described in [10]. The calculation domain has a shape of an infinite plasma cylinder with 1 cm radius and an axisymmetrical temperature profile.…”

“…The number of spatial points was chosen as a reasonable compromise between the computational time and accuracy also considering that r Á F ex varies slowly along the radius for the considered test cases. The exact calculation method is described in [10]. This provides enough points for comparison in the third step while still keeping the computation time reasonably low.…”
