Abstract

Although there are many different solution schemes proposed for multidimensional radiative transfer, reference solutions to benchmark these methods are very rare in the literature. In this paper we produced some accurate solutions for purely absorbing gray and nongray gases including H2O and CO2 byusing the discrete transfer method with sufficiently accurate T-95 quadrature set. The spectral transmittances of the mixtures of H2O and CO2 are estimated by using the narrow band model. The gray gas solutions are obtained for different absorption coefficients, and the nongray real gas solutions are obtained for different mixture fractions of Nz O and CO2. The numerical solutions presented in this paper are proved to be sufficiently accurate ascompared to the available exact solutions and they may be used as reference solutions in evaluating various solution schemes.
