Resumen
BOUDAHRI, F. et al. Effect of pressure dependence on N.E.C of Argon thermal plasmas mixed with Helium. Rev. mex. fis. [online]. 2022, vol.68, n.4, 041501. Epub 19-Mayo-2023. ISSN 0035-001X. https://doi.org/10.31349/revmexfis.68.041501.
In the present work, we have calculated the radiative transfer, it means the radiative energy that escapes from a plasma formed from a mixture of Argon-Helium. The computations take into account several pressures between 1 ≤ p ≤ 100 atm in the temperature T wide range of 5000 - 30 000 K. In the case of the plasmas is supposed to be in local thermodynamic equilibrium. Where the contributions have been treated separately in the calculation: atomic emission lines self-absorbed and not self-absorbed, continuum (radiative attachment, radiative recombination and radius). The results show that a large part of radiation is absorbed at the first crossed millimeter and also the contribution of resonance lines is very important. These are the lines which are strongly absorbed.
