Obtenção dos coeficientes de absorção a partir dos parâmetros de linha contidos no banco de dados HITEMP 2010

Abstract

The objective of this work was to obtain the absorption coefficients of H2O at different temperatures from 500 K to 2500 K, varying by 50 K, from the line parameters contained in the HITEMP 2010 database. The JavaHawks program was used to select the calculus parameters of the spectral absorption coefficient and the cross-section of the spectral absorption. With the data they were calculated database for the absorption coefficient as a function of wavenumber. Also, a graph of the divergency of the radiative heat flux was made. The results were compared with the presented by Solovjov et al. (2014) and it was found that the generated database is in accordance with the expectations. The data generated will be used in future works in line-by-line calculations and in the determination of parameters for calculations of heat transfer by radiation using spectral models.
