Absorption properties of argon arc plasma

Popis výsledku v původním jazyce

In this paper, attention has been given to the absorption properties of argon arc plasma at the pressure from 0.1 MPa to 5 MPa. The frequency interval (0.01–10) x10^15 s^(-1) has been divided into several frequency groups. Depending on the absorption properties of the medium for the given frequency group, the average absorption coefficient has been taken as either a group Rosseland or group Planck mean. These mean absorption coefficients were calculated for thermal plasma Ar as a function of plasma temperature in the range (1000, 35000) K for each of frequency groups. Different splitting procedures of the frequency interval have been used to find the optimal values of mean absorption coefficients for further calculations of radiation characteristics. Attention has been given to calculation of net emission coefficients which determine the radiation losses in the arc centre. Net emission coefficients have been derived for isothermal cylindrical plasmas of radii from 0.01 to 10 cm.
