ABSTRACT

In this work, we report the calculation of the radiative and transport properties in Ar-H2-Cu mixtures. The plasma is supposed to be in local thermodynamic equilibrium (LTE) at atmospheric pressure, for temperatures between 300 and 25000 K. In the first part, we present the bases of the study with the composition and thermodynamic properties for this type of mixture. In the second part, we propose to calculate radiative properties with two methods which are net emission coefficient in an isothermal and homogeneous medium and mean absorption coefficients based on the carving of the spectrum in some interval strips. Finally, for various mixtures, we report our results of the transport coefficients acquired by the method of Chapman-Enskog.
