ABSTRACT
The system of radiative gas dynamics governing equations requires a knowledge of the spatial distribution of the radiation flux and its divergence in order to obtain the solution, thus making it necessary to address the independent problem of radiative transport under the conditions. The vast experience gathered in the study of nongray radiation transfer and neutron transport, and particularly in developing approximation techniques. The main computational difficulty that arises is the necessity to integrate the radiative transport equations with a very small step if nongray radiation is to be taken into account properly. The problem, taking into account for nongray absorption, proves to be amenable to an exact solution if it is assumed that the absorption coefficient depends solely on the wavelength of radiation and is the same everywhere throughout the region occupied by the radiating and absorbing medium.
