Computation of net emission of ? - ? thermal plasmas
Abstract
Assuming local thermodynamic equilibrium (LTE), the total radiation which escapes from a 0022-3727/30/21/010/img8 - 0022-3727/30/21/010/img9 plasma is calculated in the temperature range between 5000 and 30 000 K. The evaluation of the net emission coefficient is performed by solving the radiative transfer equation in a cylindrical isothermal plasma taking into account line broadening phenomena. The radiation emission of methane depends mainly on the carbon species, whereas the presence of hydrogen in the mixture leads to a radiation decrease especially at high temperatures.
