EFFECT OF MOLECULES IN RADIATIVE EMISSION FROM THE THERMAL PLASMAS OF CH4−H2 MIXTURES
ABSTRAKT
The paper presents a numerical model of the radiation escaping from the thermal plasma made of the mixtures of methane CH4 and hydrogen H2. This simulation is performed at L.T.E. (Local Thermodynamic Equilibrium) at atmospheric pressure in the temperature interval from 300 to 30,000 K. The total radiation plasmas obtained by the summation of all the contributions (atomic continuum, atomic lines, molecular continuum, and molecular bands) are described in detail. In this paper, we focus on the contribution by the molecular species. Several figures are proposed to illustrate the influence of these molecules depending on the temperature, pressure, and the plasma size.
