The application of a new approximate technique for treating radiative transfer in absorbing, emitting, linear-anisotropic scattering, two-dimensional rectangular enclosures is presented. In its development, the discontinuous nature of the radiation intensity, stability of the iterative solution procedure and selection of quadrature points have been addressed. By using this approach, effects of nonuniform and spectrally dependent properties, anisotropic scattering, and reflecting surfaces can be handled effectively. Furthermore, the spatial discretization can be formed without consideration to the chosen discrete directions, permitting a complete compatibility with the discretization of the conservation equations of mass, momentum and energy. The effects of wall emission, gray-diffuse surfaces, and internal emission are considered for comparison with results available in the literature. The computed numerical results are in excellent agreement with those obtained by other numerical approaches.
