The methods of spectral integration for SLW modeling in the multicomponent gas mixtures
are considered. The direct method and the method of convolution are extended to the
multicomponent mixtures. Two new methods of spectral integration are proposed: the
method of superposition and the multiplication method. A hybrid method based on desirable
attributes of the latter two methods is also considered. The validation of the methods is
performed by the prediction of radiative transfer in isothermal homogeneous media and in a …
