The latest method for determining the absorption cross-section depending on both the local temperature and electron number density for constructing a multiband radiation model for the calculation of the Galileo probe entry flowfield was investigated. One-dimentiosional radiative transfer calculations assuming the tangent-slab approximation were carried out along the shock layer profile in the study. The multiband model well reproduced heat flux distributions, which was given by the line-by-line calculations. Two radiative heat flux distributions using two different table intervals agreed with each other, confirming that the cross section table with 14×10 intervals were sufficient for the purpose. It was shown that the method can favorably reproduce the high-fidelity radiative heat flux values given by the line-by-line shock layer profiles taken from the computed Galileo probe entry flowfield.
