The Radiation Loss of a Cylindrical Methane-Argon Plasma Arc

Calculation of the net radiation emitted by a CH(4)-Ar mixture, in a temperature range of 5,000 similar to 30,000 K with the assumption of local thermodynamic equilibrium (LTE), is conducted. Continuum and line emissions are taken into account. The radiative transfer of each line is calculated by means of an escape factor depending on the shape and broadening of the line. Assuming a cylindrical, homogeneous, and is other mal plasma, the net emission coefficient is calculated for different pressures between 1 atm and 10 atm and arc radia of 0 mm to 1 mm. Results show that the argon presence in the CH(4)-Ar mixture has a significant effect on the total radiation emitted for the temperature above 17,000 K and the results for pure argon agree with those of BAUDER and EVANS.
